title: Unable to extend LightSwitch HTML Client visual collection(`contentItem.value.data`) using jquery extend
body: <p>I am extending the <code>contentItem.value.data</code> with the Jquery <code>extend</code> but the changes are not reflected in the target object. And after sometimes it get reflected. I think something has delayed the setting the value to the particular property. </p>
  
  <pre><code>var based = contentItem.value.data[0]; //data will contain several properties and `EmployeeID-9` is one of them
  
  $.extend(based,{EmployeeID:4});
  </code></pre>
  
  <p>And now after extending the EmployeeID still has <code>9</code> but after sometimes(some delay) it has <code>4</code>.</p>
  
  <p>How can i extend the contentItem data is there any way to do this? </p>
