title: Marionette bubble event from itemview to parent layoutview?
body: <p>I have a layout view with a region, in that region I have a item view that triggers an event but it doesn't seem to be bubbled up to the layout view.  Am I doing something wrong or is this designed behavior?  I assume the itemview prefix is not added as the parent view is not a collection view?  Either way the event is never bubbled to the layout view.</p>
  
  <pre><code>layoutView = Marionette.Layout.extend({
          template: "#layout-template",
          regions: {
              titleRegion: "#job-title-region"
          },
          triggers: {
              "save:clicked" : "onSaveClicked"
          },
          onSaveClicked: function (args) {
              alert('Clicked');
          }
      });
  
  childview = Marionette.ItemView.extend({
          template: "#child-template",
          triggers: {
              "click .js-save": "save:clicked"
          }
      });
  </code></pre>
  
  <p><strong>UPDATE:</strong></p>
  
  <p>See this fiddle <a href="http://jsfiddle.net/7ATMz/11/">http://jsfiddle.net/7ATMz/11/</a> I managed to get the layout view to listen to the child event but I have to wire it up outside of the layout view itself and break encapsulation.  Can I do this in the layout view in anyway?</p>
  
  <p>Thanks,</p>
