title: google dfp pubads().refresh() not working as expected
body: <p>I'm using some of the new features in Google DFP and can't get a single add to refresh on it's own.  I can refresh all ads on the page but I can't get just one to refresh by itself.</p>
  
  <p>I've been trying the following code to get one add to refresh without luck:</p>
  
  <pre><code>   var slot1 = googletag.display('/6900315/myad2', [300, 250], 'div-2');
          googletag.pubads().refresh([slot1]);
  </code></pre>
  
  <p>Any help would be appreciated!</p>
