title: Accessing Controller from Views in Emeber
body: <p>I am building a visualization app using d3 and ember.</p>
  
  <p>Inside the template i have declared a view like this</p>
  
  <p><code>{{view 'myview'}}</code>
   where i have defined function to render the charts.
  I want to trigger these functions on data change in the controller using observes property.
  I know that all the views have the same context of the controller they are in.</p>
  
  <p>I try <code>this.controller.get('some_variable');</code>
  The output is undefined.
  How to achieve it ???</p>
