title: How to get the parent component reference
body: <p>I have a parent component:</p>
  
  <pre><code>&lt;Parent&gt;
  &lt;Child (click)=doSomething()&gt;&lt;/Child&gt;
  &lt;/Parent&gt;
  </code></pre>
  
  <p>I want to have a reference to the Parent component so that I can pass it in the method, that would trigger an event that would have a parent ref.:</p>
  
  <pre><code>doSomething() {
  // I would like to trigger the event, that would be catch elsewhere in the     app
  trigger(new ClickedEvent(referenceToParent));
  
  }
  </code></pre>
  
  <p>the event would be like:</p>
  
  <pre><code>class ClickedEvent {
  constructor (public referenceToParent: Parent) {} 
  }
  </code></pre>
  
  <p>How would I achieve that ?</p>
