I had same problem after replacing the screen myself. The power goes on and touch screen work just fine, but home button was no longer functional... After careful study, I found out that two small prongs didn't have the solid connection when assembling. It seems two prongs were bended to the opposite direction when using heater to remove the adhesive. Just gently bend them backwards to the original shape and you will be able to use the home button!
