title: jquery $.ajax success response issue
body: <p>I have a jquery $.ajax call and in my success callback, I have this</p>
  
  <pre><code>success: function(response) {
      console.log('response = '+response);
      console.log('response.validate = '+response.validate);
  }
  </code></pre>
  
  <p>Here's my console output in Firebug:</p>
  
  <pre><code>response = {"validate":true}
  response.validate = undefined
  </code></pre>
  
  <p>How the heck is response.validate equal to undefined?</p>
