title: Controller.doInit is not a function?
body: <p>In my application, we have a panel of back, next buttons that are included in every screen for navigation. From the next button, I want to call a Controller using:</p>
  
  <pre><code> myApp.app.getController('folder.MyInfoController').submitMyInfoForm(nextButtonId);
  </code></pre>
  
  <p>However, I get a TypeError: controller.doInit is not a function. I have an init method in my controller which is already working. </p>
