复选框总是显示False或True

Question

我试图理解复选框状态发生了什么。所以我有创建页面，我插入Patient当我在索引页点击Emergency到True时，我总是得到False

IndexPage.cshtml

@if (Model.Count() > 0)
{
<table class="table table-bordered table-striped" style="width:100%">
<thead>
<tr>
<th>
Doctor Full Name - CODE
</th>
<th>
Patient Full Name
</th>
<th>
Date and Time
</th>
<th>
Emergency
</th>
<th></th>
</tr>
</thead>
<tbody>
@foreach (var obj in Model)
{
<tr>
<td width="25%">@obj.Doctor.Firstname @obj.Doctor.Lastname @obj.Doctor.Code</td>
<td width="25%">@obj.Patient.FirstName @obj.Patient.LastName</td>
<td width="25%">@obj.DateAndTime</td>
<td width="25%" class="blink_me">@obj.Emergency</td>

<td class="text-center">
<div class="w-75 btn-group" role="group">
<a asp-route-Id="@obj.Id" asp-action="Upsert" class="btn btn-primary mx-2">
<i class="fas fa-edit"></i>
</a>
<a asp-route-Id="@obj.Id" asp-action="Delete" class="btn btn-danger mx-2">
<i class="far fa-trash-alt"></i>
</a>
</div>
</td>
</tr>
}
</tbody>
</table>
}
else
{
<p> No Admission Patient exists.</p>
}
