Do you mean this? [image|1501550] That is the actuator, the part that goes "click". I'm not really sure it's even fixable but perhaps there can be some form of transplant between two different home buttons. The thing is, you don't want to damage your original home button (flex or front lens) otherwise you lose TouchID capabilities. You could replace the home button completely but again you will lose TouchID.
