title: Angular-Breadcrumb: parent state's label is empty
body: <p>I'm using the <a href="https://github.com/ncuillery/angular-breadcrumb" rel="nofollow noreferrer">angular-breadcrumb module</a> to build a navigation panel.</p>
  
  <p>I have a problem displaying the parent state's dynamic <em>label</em>: when activated the <em>child's label</em> is displayed and the <em>parent's one</em> is empty. Both states use different controllers. </p>
  
  <p>What's wrong with my setup?</p>
  
  <pre><code>var parentState = {
      name: 'parentState',
      parent: 'parentParentState',
      url: '/:department_id/object/:object_id?department_name&amp;object_name',
      ncyBreadcrumb: {
          label: '&lt;% resNavCtrl.stateLabel %&gt;'
      },
      views: {
          'main': {
              controller: 'resourcesNavController',
                  controllerAs: 'resNavCtrl',
                  templateUrl: templateUrl
              }
      },
      params: {
          department_name: null,
          object_name: null
      },        
  };
  
  var childState = {
      name: 'childState',
      parent: 'parentState',
      url: '/:resourceType?resourceTypeName',
      ncyBreadcrumb: {
          label: '&lt;% resCtrl.stateLabel %&gt;'
      },
      views: {
          'main@': {
               controller: 'resourcesController',
               controllerAs: 'resCtrl',
               templateUrl: templateUrl
          }
      },
      params: { 
          resourceType: '',
          resourceTypeName: ''
      }        
  };
  </code></pre>
