Home button and ribbon behind the LCD plate are not interchangeable like with the 5s home button and charge port. They are linked to the specific device for touch ID. Is it possible the buttons and plates might have been mixed up during the swaps? Damage to the cables should prevent the home function from working as well, if the home is working it would have to be a mixup of parts or if your using a full assembly and only swapping the home button that would also cause the issue.
