Button calls via jQuery now; launches functions correctly, but...

addClasses button and showClasses button are now pressed via jQuery IDs,
and successfully launch addClasses() & showClasses within onDeviceReady.

The project works as intended on an emulator.
HOWEVER, it does not seem to work on a real LG 730 Android 4.1.2 device.
Revert "Button calls via jQuery now; launches functions correctly, but..."
