title: jqueryUI datepicker in fancybox does not work
body: <p>I have this strange problem. When I put an input with datepicker class into a fyncybox wrap, datepicker does not show up when I click on that input.</p>
  
  <pre><code>&lt;a href="#test" class="fancybox"&gt;Open&lt;/a&gt;
  &lt;div id="test" style="display:none;width:300px;"&gt;
  &lt;p&gt;
  Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque blandit, mi sed
  &lt;/p&gt;
  &lt;input type="text" class="datepicker"/&gt;
  &lt;/div&gt;
  
  $(".datepicker").datepicker();
  
  $(".fancybox").fancybox({
      openEffect  : 'none',
      closeEffect : 'none',
      afterLoad   : function() {
          this.inner.prepend( '&lt;h1&gt;1. My custom title&lt;/h1&gt;' );
          this.content = '&lt;h1&gt;2. My custom title&lt;/h1&gt;' + this.content.html();
      }
  });
  </code></pre>
