title: How to pass event objects as parameters (from handlebars template to an action in a controller)
body: <p>I am new to ember, thus I would appreciate your assistance. I want to pass an focus-out event (see bold marked text below) from my handlebars template:</p>
  
  <pre><code>{{input type="text" class="form-control" **focus-out= (action "ccFocusLost" event**) }}
  </code></pre>
  
  <p>To my action in my controller:</p>
  
  <pre><code>   ccFocusLost : function(**event**) {
          alert(event.relatedTarget.tagName);
      },
  </code></pre>
  
  <p>However, i get an undefined when I do as above. I need a way to obtain the focus-out event in order to find out which element will receive the focus after my main element loses it.</p>
  
  <p>Thanks in advance!</p>
