title: How to intercept call
body: <p>I need to use a progress bar or loader indicator and start that when I'm trying to query to Azure.
  Is this possible and how to do it. example of the query for now as you see I'm doing manualy:</p>
  
  <pre><code>var client = new WindowsAzure.MobileServiceClient('site', 'key');
  var dataTable = client.getTable('table');
  function GetAzureData(){
  progress.start();
  dataTable.take(12).where({condition:condition}).read().done(
                      function (d) {
  //fill data
                         progress.completed();
                      }, function (err) {
                          progress.completed();
                      });
  }
  </code></pre>
  
  <p>But because I have a lot of methods like this I need to intercept this when I call "where" or "read" ect and show progress (loader).</p>
