Changing parent ion-view title from child template

I have a side navigation with each ion-view containing its own tabbed tabbed navigation. My issue is the parent ion-view uses view-title to show the title, is there I way I can modify that title from a child view. For example the parent ion-view is “Category”, and when the nested tab in that ion-view is changed i might change the name to “Category: Candles” depending on what child view is being viewed.

Also, is there a way to add buttons to the main parent top nav bar from a child view?


Anybody have any idea on how to do this. I basically need to modify a parents nav bar from a child view.
