PowerDNS Dynamic Record Generation with LUA script

Dear Team,

I am working on powerdns project.
I have set up PowerDNS Server and recursor @ one of ISP, the Issue I am
facing in Generating IPV6 Reverse records.

I need your Valuable help to pinpoint my mistake.

I am using Pdns Server version 4.5.4 with gsqlite3 backend and Recursor
version is 4.5.11

I can successfully get a Static Reverse entry made in a zone file but
unable to get a Dynamic entry Answer (LUA ).

following are zone file for your ready reference,
IPv6 pool: 2001:df1:cbc0::/48
