Why does my home button on my ipad all of the sudden not work at all?
I would guess that it's broken. I would contact Apple for diagnosis and, if it's still within the warranty, repair or replacement.
I took a microfiber towel and put a small amount of alcohol on it and rubbed the home button while pushing it and it seems to work now.
It happens the same to me, sometimes I push the button and I start to push it in all the ways, without releasing it, and it starts to work for a time. There's another thread with home button issues on IOS 6. Regars.
