title: Bind a model to Radio Button in ASP.NET MVC4?
body: <p>I have a model</p>
  
  <pre><code> public class SexModel
   {
      public SexModel()
      {
  
          this.Man = "Man";
          this.Woman = "Woman";
          this.ManId = 1;
          this.WomanId = 2; 
          this.WomanSelected = this.ManSelected = false;
      }
  
      public bool ManSelected { get; set; }
      public bool WomanSelected { get; set; }
      public string Man { get; set; }
      public string Woman { get; set; }
      public int ManId { get; set; }
      public int WomanId { get; set; }
  
   }
  </code></pre>
  
  <p>create a radio button on my view </p>
  
  <pre><code> @Html.RadioButton(Model.Man,  Model.ManId, Model.ManIsSelected, 
                     new { @id = Model.ManId})
  
  
   @Html.RadioButton(Model.Man, Model.WomanId, Model.WomanSelected,
                     new { @id = Model.WomanId })
  </code></pre>
  
  <p>user can select man or woman radio buttons on register form, but why always WomanSelected and ManSelected  are both false after click submit form button in my action?</p>
