title: jQuery droppable destroy in IE11?
body: <p>I've got a drag and drop grid and I'm trying to remove the droppable when I move the mouse out of that particular row on the grid. This works totally fine in Chrome! In IE11 it throws an exception as follows:</p>
  
  <blockquote>
    <p>JavaScript runtime error: cannot call methods on droppable prior to
    initialization; attempted to call method 'destroy'</p>
  </blockquote>
  
  <p>Here's my code:</p>
  
  <pre><code>row.mouseleave(function () {
      $(".labelCell:not(.ui-draggable-dragging)", row).each(function (index, value) {
  
          $this = $(value);
          $this.droppable("destroy");
      });
  });
  </code></pre>
  
  <p>The exception is being thrown on this line: <code>$this.droppable("destroy");</code></p>
  
  <p>The question is how can I "destroy" the droppable without getting this exception?</p>
