Memory leaks

[Anj78]

I try to use this keyboard on single page anjular js application.
In my application I load content by using ng-include directive.
(I have several views with controllers and present them by using ng-include binding)

I initialize input $('#Name').mlKeyboard({ is_hidden: false });
when I change view in ng-include, the page changes, controller destroys, but keyboard still on the screen.
The Keyboard and KeyboardEvent classes are alive in heap.

How to correctly destroy mlKeyboard before I will change view?
