How do I apply active class to navbar using angular-ui-utils?

Question

I am a rank beginner with angularJS and I'm developing the ui for a single-page app in angularJS using node/bower/grunt and I have installed angular-ui-bootstrap and the route and event utils from angular-ui-utils.
I've used ng-class={active:$uiRoute} on the menu items but when a menu item is selected the active class is not applied...does $uiRoute handle this or do I need to code it separately?

Apologies for asking a dumb question...
Here is the code:

`<div class="collapse navbar-collapse">
  <ul class="nav navbar-nav">
    <li ui-route="/" ng-class="{active:$uiRoute}"><a href="#/">Home</a></li>
    <li ui-route="/about" ng-class="{active:$uiRoute}"><a href="#/about">About</a></li>
    <li ui-route="/other" ng-class="{active:$uiRoute}"><a href="#/other">Other</a></li>
  </ul>
</div>
...
<script src="bower_components/angular-ui-utils/modules/route/route.js"></script>
<script src="bower_components/angular-ui-utils/modules/event/event.js"></script>`

And

angular.module('myApp', ['ngRoute','ngResource','ui.bootstrap'])
.config(function ($routeProvider) {
$routeProvider
.when('/', {
    templateUrl: 'views/main.html',
    controller: 'MainCtrl'
  })
  .when('/about', {
      templateUrl: 'views/about.html',
      controller: 'AboutCtrl'
  })
  .when('/other', {
    templateUrl: 'views/other.html',
    controller: 'OtherCtrl'
  })
  .otherwise({
    redirectTo: '/'
  });
})

Looking through the ui-utils docs, it appears you have not injected the module dependency. Change your myApp to inject ui.utils

angular.module('myApp', [
    'ngRoute',
    'ngResource',
    'ui.bootstrap',
    'ui.utils'
])
.config(function ($routeProvider) {
$routeProvider
.when('/', {
    templateUrl: 'views/main.html',
    controller: 'MainCtrl'
  })
  .when('/about', {
      templateUrl: 'views/about.html',
      controller: 'AboutCtrl'
  })
  .when('/other', {
    templateUrl: 'views/other.html',
    controller: 'OtherCtrl'
  })
  .otherwise({
    redirectTo: '/'
  });
});
