Akai APC 64 – Creating and using a script for APC64

I am trying to create a custom script for Akai APC64. The idea is to use a Custom layout of the APC64 and map it to specific clips and sliders in Ableton Live. While creating the control template it is identifying the controller inputs from APC64 properly. However, when the script is loaded in Ableton it does not respond to the controller inputs. I can see the custom session box in live, but the sliders and pads do not seem to work.

I tried using the controller template for Korg nanoKontrol2 from the CSS website and the scripts created using it is working as expected. I am attaching the controller script json files. Could you tell me what I am doing wrong?

TIA
