Buttons and other components not working on Android 4.1, 4.3

Please I just finish building my app using Ionic 2, everything works well on Android 4.4+ but on Android 4.1 or 4.2 or 4.3 the buttons are not clickable even select doesn’t work, please is there anything I need to do to make it work?

Gulp version: CLI version 3.9.1
Gulp local:
Ionic Framework Version: 2.0.0-rc.3
Ionic CLI Version: 2.1.4
Ionic App Lib Version: 2.1.2
Ionic App Scripts Version: 0.0.45
OS:
Node Version: v6.9.1

there is no support for older devices in ionic2.
For lower support use cordova crosswalk plugin.

ok thank you…I will try that now.
