Returning the property of another model that is bound to a Model in the first model - razor

Question

I'm trying to access the Question list from within the TestModel and return the QuestionModel's Property.
I need to return it in the TestModel to determine the questions to be contained in a test, but I can't, I can't find where I went wrong.
public class TestModel
{
public int Id { get; set; }
public string Name { get; set; }
public List<QuestionModel> Question { get; set; }=new List<QuestionModel>();
}
public class QuestionModel
{
public int Id { get; set; }
public AppUser User { get; set; }
public string Question { get; set; }
public bool check { get; set; }
public List<TestModel>? Tests { get; set; } = new List<TestModel>();
}
I used TestModel as one of the tuple objects.
Since the code is long, I only shared the area where I had problems.
#model Tuple<IList<TestModel>,IList<UserViewModel>>
<table class="table table-striped">
#{
int i = 0;
}
#foreach (var item in Model.Item1)
{
<form id="form[#i]" class="container m-xl-2">
<tr id="Allquest_#i" hidden="hidden">
<td colspan="5">
<div>
<input asp-for=#Model.Item1[i].Id hidden>
#for (int indexQuest = 0; indexQuest < item.Question.Count; indexQuest++)
{
<input type="checkbox" asp-for="#Model.Item1[i].Question[indexQuest].check" checked="#Model.Item1[i].Question[indexQuest].check">
<a>#Model.Item1[i].Question[indexQuest].Question</a>
<br />
}
</div>
</td>
<td>
<button type="submit" asp-controller="Test" asp-action="DeleteQuestionToTest" formmethod="post" class="btn btn-danger">Seçili Soruları Sil</button>
</td>
</tr>
</form>
i++;
}
Here I tried to capture it as a TestModel. I tried to capture it as a list and as a single model, but I couldn't.
[HttpPost]
public IActionResult DeleteQuestionToTest([Bind(Prefix ="Item1")] IList<TestModel> tests)
{
return View();
}
How can I fix the code?

I came up with a workaround by creating a separate form and specifying it in the html of the models.
#model Tuple<IList<TestModel>,IList<UserViewModel>>
<table class="table table-striped">
#{
int i = 0;
}
<form id="MainForm" asp-controller="Test" asp-action="DeleteQuestionToTest" formmethod="post"></form>
#foreach (var item in Model.Item1)
{
<form id="form[#i]" class="container m-xl-2">
<tr id="Allquest_#i" hidden="hidden">
<input asp-for=#Model.Item1[i].Id form="MainForm" hidden>
<td colspan="5">
<div>
#for (int indexQuest = 0; indexQuest < item.Question.Count; indexQuest++)
{
<input asp-for="#Model.Item1[i].Question[indexQuest].Id" form="MainForm" hidden>
<input type="checkbox" asp-for="#Model.Item1[i].Question[indexQuest].check" form="MainForm" checked="#Model.Item1[i].Question[indexQuest].check">
<a>#Model.Item1[i].Question[indexQuest].Question</a>
<br />
}
</div>
</td>
<td>
<button type="submit" form="MainForm" class="btn btn-danger">Seçili Soruları Sil</button>
</td>
</tr>
</form>
i++;
}
I returned all the tests this was a workaround, I have no idea how to return a single test.
