I've seen this question crop up a lot when it comes to the iPhone 7 and 7 plus, and I'm going to throw in a few ideas.
One of the biggest reasons it doesn't work, is down to screen quality, copy screens just don't tend to work with the home buttons, this could be due to missing traces in the cable that don't support it, or could be something else.
I've used original refurbished with every repair and never had one issue so far.

When removing the button from the original, I know people say they remove it carefully, but the home button removal procedure is a little more difficult compared to previous iPhones, especially since the extension cable isn't stuck down, this requires you to get a spudger and hold the extension down whilst unplugging the button.

You also mentioned that the home button also didn't work on the original screen either, this may be because you damaged the home button flex, or you have damaged the extension cable on the original screen, I see a lot of people lay the screen flat after they have opened the iPhone, this causes stresss on the flex and may break traces inside that cable, or again, may have been broke during removal of the home button.
Always try to use original or original refurbish, if this doesn't work, it may be the extension cable that's faulty, if it doesn't work with another replacement, you may have damaged the home button itself.
Also check that you haven't placed the bracket under the shield, it needs to be on top of the shield.
