Native keyboard accessory bar buttons callback

[umairrafiq1133]

@EddyVerbruggen I am facing issue with accessory bar buttons and there's no documentation for that.
I am using a text area where I have to add data-nativekeyboard='configureNativeKeyboard'

Now as I am using angularJS and this is one of my view, I want to add a function from my controllers scope as reference to data-nativekeyboard also callbacks of my accessory bar buttons will be in my controller. But when I do this, it gives error saying it couldnt find variable configureNativeKeyboard.

I have also tried configureNativeKeyboard() but it didnt work either.

If I add this function as global function in my index.html, it works but then I cant use it callbacks in my controller.

I have also tried to add this in my view by using inline object but then again I cant have my callbacks in controller.
