Razor單選按鈕不起作用（ASP.NETMVC）

我正在嘗試使用 .NET/C# 和 Razor 創建一個 ASP.NET MVC 應用程式來完成我的課程作業。

我想創建一個有測驗的應用程式，所以我使用 SQL 獲取問題及其替代方案，發送到視圖TempData并使用兩個 for 來瀏覽這些結構，就像在填寫測驗后我需要發送資訊到控制器。

基本上我需要的是AlternativaEscolhida用真或假填充并將其發送到控制器

控制器

public IActionResult ValidaRespostas(AvaliacaoModel model)
{
        try
        {
            if (ModelState.IsValid)
            {
            }
        }
        catch (Exception e)
        {
            TempData["Messege"] = "Error"   e.Message;
        }

        return View();
}

型號 Avaliacao型號

using PoupaAiMVC.Data.Entities;
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Threading.Tasks;

namespace PoupaAiMVC.Models.Questionario
{
    public class AvaliacaoModel
    {
        [Required]
        public List<Questao> Questoes { get; set; }
        [Required]
        public List<Alternativa> Alternativas { get; set; }
    }
}

物體Questao：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace PoupaAiMVC.Data.Entities
{
    public class Questao
    {
        public int IdQuestao { get; set; }
        public string Enunciado { get; set; }
        public int Imagem { get; set; }
        public TipoQuestao TipoQuestao { get; set; }
        public Nivel Nivel { get; set; }
        public List<Alternativa> Alternativas { get; set; }

        public static implicit operator List<object>(Questao v)
        {
            throw new NotImplementedException();
        }
    }
}

物體Alternativas：

public class Alternativa
{
    public int IdAlternativa { get; set; }
    public string alternativa { get; set; }
    public string correta { get; set; }
    public int Id_Questao { get; set; }
    public bool AlternativaEscolhida { get; set; }
}
