Samsung Galaxy Grand Screen replacement

[AC Question]

My outer glass screen cracked , but the touch was working well, I got a glass digitizer replacement anyways because I ripped off the digitizer ribbbon while seperating screen from lcd.

I am not able to post the replacement part link in this post as I do not have enough posts

I followed all possible videos for replacement. Now my touch is unresponsive after fixing the digitizer. Why is this happening?
Should I buy a new part? Everything else works fine except touch.
My lcd is clean, There is no debris.

Please help. !!
