handling action in view not router

I have a view that has expandable/collapsable content that I'd like to be able to toggle by clicking the on the table row. Before pre1.0, I had this in the template:

<tr {{action "expand"}}>

which was previously handled on my view:

App.ContentRowView = Em.View.extend({
   templateName: 'ember/templates/content/row',
   expand: function() {
      this.set('isExpanded', !this.get('isExpanded'));
   },
   isExpanded: false
});

However, after upgrading to pre1.0 the action is now fielded directly by the router. This makes sense in a lot of situations, but in this case the expansion is really a view concern. I've tried just replacing this with a click event handler without luck.

Is there a best practice on how to handle a view concern event like this with pre1.0?
