title: Accessing Backbone.js view objects with Jquery UI droppable
body: <p>I've got a drag and drop UI basically working with jquery ui and backbone.js. My view looks like:</p>
  
  <pre><code>render: function()
  {
      $(this.el).html(ich.template_bucket(this.model.toJSON()));
  
      $(this.el).draggable(
          {
              helper: "clone"
          }
      );
  
      var that = this;
      $(this.el).droppable(
          {
              hoverClass: 'ui-state-hover',
              drop: function( event, ui )
              {
                  var from_bucket_id = ui.draggable.attr('id');
                  var to_bucket_id = $(that.el).attr('id');
              }
          }
      );
  
      return this;
  },
  </code></pre>
  
  <p>I can access the <em>dropped on</em> view via <code>that</code>, but is it possible to get a hold of the dragged view inside the droppable callback?</p>
  
  <p>Alternatively, what I'm ultimately trying to do is update the two views (the dragged and dropped into views) when something happens inside a modal window that pops up (another backbone view) after the drag happens. This view doesn't share models with the two views, so I'm not sure if there's any events I can listen to.</p>
