Pushing the home button had no results unless it was pushed very hard
The new parts ordered were installed without concern. After cleaning off the glue strips, I temporarily installed the digitizer screen and the home button still did not function as expected. Made some measurements and found that the two pins that are on the charge assy were not contacting the home button control board. The two angled screws from the charge harness were removed. A piece of black tape was used under the charge harness to lift it slightly higher. Parts were reinstalled and it then functioned as expected.
Make sure to totally clean off all old glue strips. Also clean off old glue residue the best you can. This good prep will insure good bonding of the digitizer screen to the ipad housing. Also make sure all smudges are cleaned off the LCD screen and inner digitizer screen before final installation. Good luck.. This procedure is very easy if you just take your time.
