title: Cannot raise InteractionRequest in OnNavigatedTo Method?
body: <p>I'm navigating to a view when its module gets loaded:</p>
  
  <pre><code>public void OnImportsSatisfied()
  {
      this.ModuleManager.LoadModuleCompleted +=
              (s, e) =&gt;
              {   
                  if (e.ModuleInfo.ModuleName == EmailModuleName)
                  {
                      this.RegionManager.RequestNavigate(
                          RegionNames.MainContentRegion,
                          InboxViewUri);
                  }
              };
      }
  </code></pre>
  
  <p>when I navigate to this view I want to raise a NotificationRequest (and his PopupWindow); this method is defined in the ViewModel:  </p>
  
  <pre><code>void INavigationAware.OnNavigatedTo(NavigationContext navigationContext)
  {
      MyInteractionRequest.Raise(...);
  }
  </code></pre>
  
  <p>Through debugging I discovered that the InteractionRequest has no subscribers to its Raised event for the first time I navigate to the view, and that's why no interaction window is shown. In order to make the InteractionRequest work I need to navigate to another view and then go back.
  Why does this happend? Does the view get created too late after the viewmodel and so it cant subscribe the InteractionTrigger to the Interaction Request?</p>
