title: MultiSelectList doesn't return view data
body: <p>I have a multi select list in my View to send to controller a list of Users. My View receives the users, but is not sending back to controller. What am I missing?</p>
  
  <p>My controller is:</p>
  
  <pre><code>        // GET:
      public ActionResult Create(User user)
      {
          ViewModel model = new ViewModel();
  
          Interaction interact = new Interaction();
  
          model.Users= Repository.GetUsers();
          model.Interacao = interact;
  
          return View( model );
      }
  </code></pre>
  
  <p>In my view, the listBox is:</p>
  
  <pre><code>@Html.ListBoxFor( model =&gt; model.Users, new MultiSelectList( Model.Users, "Id", "Name" ) )
  </code></pre>
  
  <p>Can Anyone tell me where I am wrong?</p>
