title: Attach ExtJS MVC controllers to DOM elements, not components
body: <p>Is there a way to use the Ext.app.Controller control() method, but pass in a DOM query? I have a page that contains standard  links and would like to add a click handler to them even though they were not created as Ext Buttons.</p>
  
  <p>I've tried </p>
  
  <pre><code>Ext.define('app.controller.TabController', {
      extend: 'Ext.app.Controller',
  
      init: function() {
          console.log("init");
          this.control({
              'a': {
                  click: this.changeTab
              }   
          });
      },
  
      changeTab: function() {
          alert("new tab!");
      }   
  });
  </code></pre>
  
  <p>But clicking on links does not fire the alert. </p>
  
  <p>Is there a way to specify a CSS selector with this.control? Or does it only work with components?</p>
