After taking apart my Power button it wont click anymore?

Hey ,

So I recently purchased a used midframe with parts from ebay

everything worked but the power button would not click so I toook the two screws which held the button in place and i couldnt figure it out

So i did the same to another midframe I had which did click to see any diffrence

After putting the one the clicked back together it refuses to click

its just like the one that didnt click and I cant figure out whats wrong with it

the black dot is there and I followed the guide on ifixit and it WAS working

Someone please help me

thanks alot
