Android/Chrome: Textbox accepts all characters as input

[babartareen]

Looks like on android, jquery events keypress and keydown are not triggered and as a result, input validation logic is broken.

Tested on:
Stock Android (7.1.2)
Chrome (58.0.3029.83)
Keyboard: Gboard (6.3.28.15901150-1rm64-v8a)
