title: Can't bind model to route values of DevExpress button
body: <p>I can't seem to get a model from my view to pass back to a controller action using the route values of a DevExpress button. Here is the button:</p>
  
  <pre><code>Html.DevExpress().Button(btn =&gt;
  {
      btn.Name = "btnSubmit";
      btn.Text = "Search";
      btn.Width = Unit.Pixel(100);
      btn.UseSubmitBehavior = true;
      btn.RouteValues = new {Controller = "ProjectSearch", Action = "PerformSearch", projectSearchParametersModel = Model};
  }).Render();
  </code></pre>
  
  <p>Then I have this controller action:</p>
  
  <pre><code>public ActionResult PerformSearch(IProjectSearchParametersModel projectSearchParametersModel)
  { /* do search */ }
  </code></pre>
  
  <p>Unfortunately projectSearchParametersModel is null every time I get into that action and I can't figure out why the model won't pass through.</p>
