title: Concat ajax success respone
body: <p>Here is my ajax request success function</p>
  
  <pre><code>function(res){
     var proposedValue='res.'+ res.ProposedFor;
     $('#MyDynamicDropdown').val(proposedValue);
  }
  </code></pre>
  
  <p>Here, proposedValue does return </p>
  
  <blockquote>
    <p>res.AreaId</p>
  </blockquote>
  
  <p>But it doesn't set my value in the dropdown.
  If I use</p>
  
  <pre><code> $('#MyDynamicDropdown').val(res.AreaId);
  </code></pre>
  
  <p>That works fine.But I can't use this because I don't know what has been propose for.
  Thanks hope you understand my issue.</p>
