The notifications aren't update using the API of universal work list

Question

We use in the portal home a development iview  that works with de API of Universal Work List. This iview shows the number of notifications and tasks. While the number of tasks are updated correctly, the number of notifications are not refreshed. The only way to update the number of notifications is going and refreshing the Universal Work List iView provided by SAP.
The API that we are using not support this case? Any suggestion?
We haven’t found information about this.
Our system version is 7.00 SP14
We attachment the call that we‘ve used.
      try {
        notificaciones = tareas = 0;
        IUWLService uwlService =
          (IUWLService)PortalRuntime.getRuntimeResources().getService(
            IUWLService.ALIAS_KEY);
        UWLContext uwlContext = new UWLContext();
        IUser user = componentRequest.getUser();
        uwlContext.setUser(user);
        uwlContext.setAllowBackEndConnections(true);
        uwlService.beginSession(uwlContext, -1);
        IUWLItemManager itemManager = uwlService.getItemManager(uwlContext);
        QueryResult result =
          itemManager.refreshCacheAndGetItems(uwlContext, null, null, null);
        ItemCollection collection = result.getItems();
        for (int i = 0; i < collection.size(); i++) {
          Item item = collection.get(i);
          if ((item.isUnRead() || item.isNew())
            && item.getItemType().startsWith("uwl.notification")) {
            notificaciones++;
          } else if (
            (item.isUnRead() || item.isNew())
              && item.getItemType().startsWith("uwl.task")) {
            tareas++;
        uwlService.endSession(uwlContext);
      } catch (UWLException e) {
        e.printStackTrace();

Thank you very much for your quick answer...
But I think that you don't understand me. We can read notifications number but not in real time because they are not updated until we go to the UWL and we force there an update. We want to show in real time the number of notifications that a user has.
Does anybody how to update/refresh this using the API?
Thanks for your suggestions
