title: How to wait till an element appears after an AJAX call using capybara-webkit?
body: <p>The capybara method, <code>wait_until</code> doesn't seems to work for capybara-webkit.  Is there any alternate solution for that, or any Javascript implementations?</p>
  
  <p>Intentionally need some replacement for <code>sleep</code>, e.g. <code>sleep 2</code>.</p>
