zend 2: Trying to pass around a ViewModel between methods

I spent a little while trying to figure out how to implement a sub menu bar and eventually decided all I really want is a little helper method that appends my template to the current view instead of an actual view helper:

//To use in any action requiring the sub navbar to be displayed
protected function addSubNav(ViewModel $view) {
    $subNavView = new ViewModel();
    $subNavView->setTemplate('helpdesk/helpdesk/subNav');
    $view->addChild($subNavView, 'subNav');

    return $view;
}

But when I call it in a method like this $this->subNav in my template is null:

public function indexAction() {
    //return new ViewModel();
    $this->addSubNav(new ViewModel());
}

When doing $this->subNav in index.phtml is NULL, why is that?

addSubNav() should be returning the view which I appended a template to.

You don't return your view model a the end of your action

public function indexAction() {
    return $this->addSubNav(new ViewModel());
}
