Angularjs rootscope not updating ngClass when route change

On $routeChangeStart I like to apply of-h class and on $routeChangeSuccess either I like remove of-h class or change it to of-v class. Now only of-h class get applied.

HTML

<div class="container-outer" ng-class="addClassOnRouteChange">
  <div class="container" ng-view autoscroll="true" ng-class="fadeNgView">
    <!-- Views will be rendered here -->
  </div>
</div>

JS

angular.module('starter', ['ngRoute', 'ngAnimate', 'myApp.controllers'])

  .run(['$window', '$location','$rootScope', function ($window, $location, $rootScope) {
    $rootScope.fadeNgView = '';

    $rootScope.$on('$routeChangeStart', function() {
      //event button item list to move forward
      $rootScope.next = function() {
        console.log('start');
        $rootScope.fadeNgView = 'fade-ng-view';
        $rootScope.addClassOnRouteChange = 'of-h';
      }
    });

    $rootScope.$on('$routeChangeSuccess', function (event, current, previous) {
      $rootScope.addClassOnRouteChange = 'of-v';
    });
  }]);

Try This :

$rootScope.$apply(function(){
    $rootScope.addClassOnRouteChang‌​‌​e = 'of-h';
});
