No other home button will return touch ID functionality other than the original home button that came with your phone. Does the button look damaged? If not, it could be the cable or connector that plugs into the home button is damaged. This isnt usually the case, but it’s worth a shot to remove the original home button from the screen and install it on a new screen to test. If that does not work, the only option to regain touch ID functionality it to take it to an Apple store. In the past, they have been able to replace the home button and reprogram it to restore touch ID functionality.
