You mean the home button is a simple home button, and if you put your finger on it for touch-ID nothing whatsoever happens, not even rejected as an unknown finger, and you can't setup a new finger because it is not "seen"? Check it the relevant function is turned on under Settings / Touch ID & Passcode. Turn it off then go back in and turn it on again to force resaving the settings. If this is OK wipe the home button with a soft cloth to be sure it is clean and try to setup a new finger. If it still fails I think your touch sensor has failed and you need to visit the Apple Store for a fix. Hope you have warranty or Applecare
