Refactor Battery Chart View State Controll

Browse Source 
When users click the battery chart, the orignal behavior is that the view changes the state by itself.
This cl refactors the bahavior to that the view callbacks to the controller, and
the controller changes the view's state.
In this way, the controller is the only source of truth of the state.
This meets the controller-view model.
