title: CasperJS can not trigger twitter infinite scroll
body: <p>I am trying to get some information from twitter using <strong>CasperJS</strong>. And I'm stuck with infinite scroll. The thing is that even using jquery to scroll the page down nothings seems to work. Neither scrolling, neither triggering the exact event on <code>window</code> (smth like uiNearTheBottom) doesn't seem to help. 
  Interesting thing - all of these attempts work when injecting JS code via js console in FF &amp; Chrome. 
  Here's the example code :</p>
  
  <pre><code>casper.thenEvaluate(function(){
      $(window).trigger('uiNearTheBottom');
  });
  </code></pre>
  
  <p>or </p>
  
  <pre><code>casper.thenEvaluate(function(){
      document.body.scrollTop  =  document.body.scrollHeight;
  });
  </code></pre>
