title: TextBoxFor value not passed to model when disabled
body: <p>I have a disabled input-field displaying data from a model.</p>
  
  <pre><code>&lt;div class="form-group"&gt;
                      @Html.LabelFor(model =&gt; model.first_name, "Förnamn", new
              {
                  @for = "inputFirstname",
                  @class = "col-lg-3 control-label"
              })
                      &lt;div class="col-lg-9"&gt;
                          @Html.TextBoxFor(model =&gt; model.first_name, new
                  {
                      @type = "text",
                      @class = "form-control",
                      @id = "inputFirstname",
                      text = Html.DisplayNameFor(model =&gt; model.first_name),
                      disabled="disabled"
                  })
                      &lt;/div&gt;
                  &lt;/div&gt;
  </code></pre>
  
  <p>I can submit this data to a controlelr method:</p>
  
  <p>[HttpPost]</p>
  
  <pre><code>public ActionResult Index(RegistrationModel RegistrationModelViewModel)
  {}
  </code></pre>
  
  <p>When i add <code>disabled="disabled"</code> the first_name data is null, if i remove it i get the correct data.</p>
  
  <p>What am i doing wrong?</p>
