title: ngClick events not firing in Angular 1.5.5 component
body: <p>Why doesn't clicking the button described in the template below work as expected? <a href="https://toddmotto.com/exploring-the-angular-1-5-component-method/" rel="nofollow">This blog post does the exact same thing</a>.</p>
  
  <pre><code>'use strict';
  
  angular.module('core').component('foo', {
      bindings: {
          items: '&lt;',
      },
      controller: function() {
          function fire() {
              console.log('hello');
          }
      },
      template: "&lt;button type='button' ng-click='$ctrl.fire();'&gt;Test&lt;/button&gt;"
  });
  </code></pre>
  
  <p>Edit: Added more clarity to the question</p>
