The helpers are set and work fine. However, $html->link() does not
work when called within a function in the view.
As for where the logic is written: this is an element that appears in
all admin tools throughout the site. requestAction() would allow me to
put some of the logic in the controller, however since this is an
array used only for constructing a menu, I don't really see any
advantage to that.
