title: TextBoxFor value not updating after post
body: <p>I have a simple strongly typed view, but I cant seem to update a textbox on my form after a post.  </p>
  
  <p>Here is my model:</p>
  
  <pre><code>public class Repair
    {
      public string Number { get; set; }      
    }
  </code></pre>
  
  <p>And in my view is a TextBox:</p>
  
  <pre><code>   @Html.TextBoxFor(x =&gt; x.Number)
  </code></pre>
  
  <p>I'm trying to update the textbox after a post to my controller:</p>
  
  <pre><code> [AcceptVerbs(HttpVerbs.Post)]
          public ActionResult Index(Repair r)
          {
  
            r.Number = "New Value";
  
            return View(r);
  
          }
  </code></pre>
  
  <p>Even though I'm setting Number to a new value, the text in the textbox does not change.  What am I doing wrong? </p>
