title: Using {{action}} to target an event in a different route
body: <p>Assuming I have a route with an event like</p>
  
  <pre><code>App.FooRoute = Ember.Route.extend({
    events: {
      anAction: function(){
      }
    }
  })
  </code></pre>
  
  <p>How do I trigger it from the view of another route/controller ?</p>
  
  <pre><code>&lt;a {{action anAction target='???'}}&gt; a link &lt;/a&gt;
  </code></pre>
