Default [Q] Klick App not working in Moto G

I got one of these Pressy Button Clone from Gearbest and tried to install the Klick App to work on Moto G phone. Installation of app is fine, and the app lets user define which app to be launched in one click, two click, or three click modes once the device is secured at the earphone plug. The app only gets to the point of confirming whether it's earplug or the device in the microphone jack, but remains unresponsive, i.e., not launching the corresponding app.

Phone is Boost Mobile Moto G flashed to pageplus with Verizon firmware & I did not do any 4.4.4 update (manually disable ota when flashing).

Anything I can do to get it to work?
