Home button not working after replacing dock connector

Hi all,

I recently replaced an iPhone 5 dock connector and everything is working fine except the home button. I'm 100% positive that both the dock connector and home button flex cable work, because I tested both by pushing the home button flex cables gold connectors on the dock connectors pins. I did this ^ with the screen tilted.

However, when I put the screen back on the right way the two connecting parts don't seem to touch each other, since the homebutton doesn't work. I tried to bend the dock connector pins slightly up, but without success so far.

Is there anybody who has any ideas how to solve this?

Thanks in advance.
