iPad Mini 2 Wifi - Screen Works, No Response - Should I Glue it Down?

All right. This may be a stupid question, but after taking 3 full hours to pull the dang iPad apart and pick glass pieces out, I don't want to have to do that again. So I'm asking questions before I take the next step.

I've got the new screen attached and everything put back together. All, that is, except for removing the tape from the edges and sticking it down again.

So I turned it on, and the LCD works just fine. I get to the lock screen, but the home button doesn't do anything, and the touchscreen doesn't do anything. Is this something that will be fixed by completing the last step of gluing it all down? Or is something disconnected still?

Thanks!
