title: JQuery .click() does not work in new sortable item
body: <p>I have JQuery UI Sortable+Draggable lists, and i use JQuery .click() for all sortable items, but if i drop new item from draggable list to sortable list, this item do not trigger .click() event.</p>
  
  <pre><code>$(#sortable li).click(function(){
      alert('Sortable item clicked');
  });
  </code></pre>

  <p>Why?</p>
  
  <hr>
  
  <p>Okay, i'm replace .click() to .on('click')</p>
  
  <p>And my elements have close button with class .remove and again this does not work for new elements: </p>
  
  <pre><code>$('#sortable li').on('click','.remove',function(){
      $(this).parent().remove();
  });
  </code></pre>
