title: routeChangeStart is not fired when route changed
body: <p>I have this code snippet below (ionic framework) but <code>routeChangeStart</code> is not printed when i'm navigating around.</p>
  
  <pre><code>.run(function($ionicPlatform, $rootScope, $location) {
    $ionicPlatform.ready(function() {
      if (window.cordova &amp;&amp; window.cordova.plugins.Keyboard) {
        cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
      }
      if (window.StatusBar) {
        StatusBar.styleDefault();
      }
    });
  
    $rootScope.$on('$routeChangeStart', function(event, next, current) {
      console.info('[event] routeChangeStart...');
    });
  })
  </code></pre>
