body: <ol>
  <li><p>What's the relationship between Controllers and views ? How to organize them properly ? </p></li>
  <li><p>How dose the Controller work ? Dose every view check if there is a Controller listens to its events when activating ?</p></li>
  <li><p>For example,there are many views,should i put all the event handlers in one Controller or just create a Controller for each view ?</p></li>
  <li><p>In my current project,we do not use Controller while just add the needed event handlers in the listeners config of the component.It seems everything gose well.So,is there a need to use Controller?</p></li>
  <li><p>Can someone give me some usefull MCV examples ? I just wander how the Controller works in the MVC pattern.</p></li>
