pass the data out of #Model to a form in the same razor page

I want to pass the value of #item.Id to a form out of this loop which is in the same razor page
#foreach (var item in Model.GetContracts)
{
<tr>
<td>#item.Plate</td>
<td>#item.Cname</td>
<td>#item.CheckIn.ToString("dd/MM/yyyy")</td>
<td>#item.CheckOut.ToString("dd/MM/yyyy")</td>
<td>#item.Price</td>
<td>#item.Paid</td>
<td>#item.Deposit</td>
<td>#item.Note</td>
<td>#item.Id</td>
<td><Button type="button" class="btn btn-success" data-toggle="modal" data-target="#Returned" onclick="getId">إغلاق العقد</Button></td>
<td><a class="btn btn-warning" asp-page="Returned" asp-route-Id="#item.Id">تجديد</a></td>
</tr>
}
I want to place the #item.Id in asp-route-id="#item.Id"
<!-- Modal for returned -->
<div class="modal fade" id="Returned" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true">
<div class="modal-dialog modal-lg" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLongTitle"></h5>
<button type="button" cl ass="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<form method="post" asp-page-handler="Returned" asp-route-id="">
<input type="date" asp-for="#Model.Update" />
<input type="submit" class="btn btn-primary" />
</form>
</div>
</div>
</div>
</div>
ps: i cant put the form in the loop because it will always read the #item.Id of the first item in list because 'div cant be nested in a tr or table'

You can add the form as a separate column for your table and pass your id there.
#foreach (var item in Model.GetContracts)
{
<tr>
<td>#item.Plate</td>
<td>#item.Cname</td>
<td>#item.CheckIn.ToString("dd/MM/yyyy")</td>
<td>#item.CheckOut.ToString("dd/MM/yyyy")</td>
<td>#item.Price</td>
<td>#item.Paid</td>
<td>#item.Deposit</td>
<td>#item.Note</td>
<td>#item.Id</td>
<td><Button type="button" class="btn btn-success" data-toggle="modal" data-target="#Returned" onclick="getId">إغلاق العقد</Button></td>
<td><a class="btn btn-warning" asp-page="Returned" asp-route-Id="#item.Id">تجديد</a></td>
<td>
<div class="modal-body">
<form method="post" asp-page-handler="Returned" asp-route-id="#item.id">
<input type="date" asp-for="#Model.Update" />
<input type="submit" class="btn btn-primary" />
</form>
</div>
</td>
</tr>
}

As #Yuri said, you could put the model popup inside the TD and inside the foreach loop. But you will find it will still just call first model, since the data-target="#Returned" just set target for the #Returned to avoid this action, I suggest you could try to modify your codes to use for loop instead of using the foreach and set the each row's return model popup id with return_#i.
More details, you could refer to below codes:
#for (int i=0; i<Model.Count; i++)
{
<tr>
<td>#Model[i].Plate</td>
<td>#Model[i].Cname</td>
<td>#Model[i].CheckIn.ToString("dd/MM/yyyy")</td>
<td>#Model[i].CheckOut.ToString("dd/MM/yyyy")</td>
<td>#Model[i].Price</td>
<td>#Model[i].Paid</td>
<td>#Model[i].Deposit</td>
<td>#Model[i].Note</td>
<td>#Model[i].Id</td>
<td><Button type="button" class="btn btn-success" data-toggle="modal" data-target="#Returned_#i" onclick="getId">إغلاق العقد</Button></td>
<td><a class="btn btn-warning" asp-page="Returned" asp-route-Id="#Model[i].Id">إغلاق العقد</a></td>
<td><a class="btn btn-warning" asp-page="CheckOut" asp-route-Id="#Model[i].Id">تجديد</a></td>
<td>
<div class="modal fade" id="Returned" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true">
<div class="modal-dialog modal-lg" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLongTitle"></h5>
<button type="button" cl ass="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<form method="post" asp-page-handler="Returned" asp-route-id="#Model[i].Id">
#item.Id
<input type="date" asp-for="#Model[i].Update" />
<input type="submit" class="btn btn-primary" />
</form>
</div>
</div>
</div>
</div>
</td>
<td>
<div class="modal fade" id="Returned_#i" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true">
<div class="modal-dialog modal-lg" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLongTitle"></h5>
<button type="button" cl ass="close" data-dismiss="modal" aria-label="Close">

I've created a modal component and that doesn't work

I'm new in coding with ASP.NET Core. I created a CRUD functions in my application and then i decided to change some rules like Create New do not navigate to another tab it will be navigated to a component modal. So I did the steps that it shown in a tutorial but I didn't get a result .
Here's the page :
This is the code in index.cshtml:
#model IEnumerable<PermissionManagement.MVC.Models.Segment>
#{
ViewData["Title"] = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<div id="PlaceHolderHere"></div>
<button type="button" class="btn btn-primary" data-toggle="ajax-modal" data-target="#addSegment" asp-action="_SegmentModelPartial" data-url="#Url.Action("Create")"> Create </button>
And this is the code wrote it in SegmentModelPartial:
#model Segment
<div class="modal fade" id="addSegment">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="addSegmentLabel">Modal title</h5>
<button type="button" class="btn-close" data-dismiss="modal" aria-label="Close">
<span>x</span>
</button>
</div>
<div class="modal-body">
<div class="row">
<div class="col-md-12">
<form asp-action="Create">
<div asp-validation-summary="ModelOnly" class="text-danger"></div>
<div class="form-group">
<label asp-for="SName" class="control-label">Nom</label>
<input asp-for="SName" class="form-control" />
<span asp-validation-for="SName" class="text-danger"></span>
</div>
<div class="row">
<div class="col-md-6">
<div class="form-group ">
<label asp-for="SRang" class="control-label">Rang</label>
<input asp-for="SRang" class="form-control" />
<span asp-validation-for="SRang" class="text-danger"></span>
</div>
</div>
</form>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary" data-save="modal">Save changes</button>
</div>
</div>
</div>
</div>
This is my code in site.js:
$(function () {
var PlaceHolderElement = $('#PlaceHolderHere');
$('button[data-toggle="ajax-modal"]').click(function (event) {
var url = $(this).data('url');
$.get(url).done(function (data) {
PlaceHolderElement.html(data);
PlaceHolderElement.find('.modal').modal('show');
})
})
PlaceHolderElement.on('click', '[data-save="modal"]', function (event) {
var form = $(this).parents('.modal').find('form');
var actionUrl = form.attr('action');
var sendData = form.serialize();
$.post(actionUrl, sendData).done(function (data)){
PlaceHolderElement.find('.modal').modal('hide');
})
})
})
And finally this is the controller:
[HttpGet]
public IActionResult Create()
{
Segment seg = new Segment();
return PartialView("_SegmentModelPartial", seg);
}
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Create(Segment segment)
{
_context.Add(segment);
await _context.SaveChangesAsync();
return PartialView("_SegmentModelPartial", segment);
}

How to create new form when clicking button in asp.net mvc or jquery?

I have a card and what i want to do, is when a user click(create course) button it must generate new content(asp.net mvc) or dashboard that is empty. I have some ideas around this. Let me share below;
<div class="row">
<div class="col-xs-3 ml-auto">
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal">
Start New Course
</button>
</div>
</div>
<!-- Modal -->
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">Start New Course</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="form-group">
<label for="CourseName" class="col-sm-2 col-form-label">CourseName:</label>
<div class="col-sm-6">
#Html.EditorFor(model => model.CourseName, new { htmlAttributes = new { #class = "form-control", autofocus = "autofocus", placeholder = "CourseName" } })
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Cancel</button>
<button type="button" class="btn btn-primary">Create Course</button>
</div>
</div>
</div>
</div>
// Jquery
<a class="btn btn-large btn-success" id="fire" href="/Controller/Courses.chtml#">Create Courses</a>
$('#fire').on('click', function (e) {
// dont know what to put here....?
})
I dont know if my logic is wrong and need some ideas around. Meaning what i want when i click the create button from the modal form it must take me to the new content(asp.net mvc). Something along this line

Change the href value, replace the ActionResultName and ControllerName, see below:
<a class="btn btn-large btn-success" id="fire" href="#Url.Action("ActionResultName","ControllerName")">Create Courses</a>

Partial View Does not render correctly with dynamic id?

i am trying to render partial view(reusable) in order to delete customer with cus_id within table(list of Customers)
but every time i submit form only first row id is submitting please tell me correct solution.
#foreach (var item in Model)
{
....
<td>
#await Html.PartialAsync("~/Views/Shared/Modal.cshtml", item.cus_id)
#*<partial name="~/Views/Shared/Modal.cshtml" for="#item.cus_id"/>*#
</td>
}
Here is My View
#model int
<span>
<i class="fas fa-trash-alt" title="Delete"></i>
</span>
<div id="myModal" class="modal fade" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header ">
<h4 class="modal-title">Warning</h4>
<button type="button" class="close" data-dismiss="modal">×</button>
</div>
<div class="modal-body">
<form asp-action="Delete" asp-route-id="#Model" method="post">
<span>
<span><b>Are you sure you want to delete?</b></span>
<button type="submit" class="btn btn-danger">Yes</button>
No
</span>
</form>
</div>
</div>
</div>
</div>

The problem is in your partial view.
<i class="fas fa-trash-alt" title="Delete"></i>
You used the id selector, it will always select the first modal which id is "myModel". While all the modals' ids are the same. So, every time you submit, only the first row id is submitting.
You can apply the cus_id to the modal id to distinguish which modal should be opened.
<span>
<i class="fas fa-trash-alt" title="Delete"></i>
</span>
<div id="myModal_#Model" class="modal fade" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header ">
<h4 class="modal-title">Warning</h4>
<button type="button" class="close" data-dismiss="modal">×</button>
</div>
<div class="modal-body">
<form asp-action="Delete" asp-route-id="#Model" method="post">
<span>
<span><b>Are you sure you want to delete #Model?</b></span>
<button type="submit" class="btn btn-danger">Yes</button>
No
</span>
</form>
</div>
</div>
</div>

MVC bootstrap popup opens multiple times

When I click in a button to open my popup form, it seems that it is being opened multiple times and in the browser console I get the error "(3) Uncaught TypeError: Cannot read property 'find' of null". What am I missing?
View containing the button:
<script src="~/Scripts/myscripts/JobOffers/JobOfferPopup.js"></script>
<div id="createJobOfferModal"></div>
<div id="jobOfferButtonsBar">
<div style="float:left; padding: 0px 5px 5px 5px;">
<a class="btn btn-default" id="createJobOfferBtn" href="" data-url="#Url.Action("CreateOrUpdate", "JobOffers", new { jobOfferId = 0 })">Create</a>
</div>
</div>
Popup View Code:
<div class="modal fade bs-example-modal-lg jobOfferForm" tabindex="-1" role="dialog" aria-labelledby="createJobOffer" aria-hidden="true">
<div class="modal-dialog modal-lg" style="overflow-y:auto; max-height:70vh">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title" id="createJobOfferLabel"> #Model.PopupTitle </h4>
</div>
<div class="modal-body" data-val="5">
<form class="form-horizontal" role="form">
<div class="form-group" style="display:none;">
<label class="col-sm-2 control-label">#Html.LabelFor(model => model.Id)</label>

</div>
</div>
<div class="form-group">
<label class="col-sm-2 control-label">#Html.LabelFor(model => model.Client) </label>

<button type="button" class="btn btn-primary" id="saveJobOfferBtn" data-url="#Url.Action("CreateOrUpdate", "JobOffers" )">Save changes</button>
</div>
</div>
</div>
</div>
Jquery Code:
$(document).ready(function () {
$('#createJobOfferBtn').click(function () {
$.ajax({

type: 'GET',
cache: false,
success: function (result) {
console.log("opened");
$("#createJobOfferModal").html(result).find('.modal').modal({
