netopeer2: callback failed

Hi all I have written a sample callback and installed my sample yang model, but when I want to edit its config using edit-config --target running --config netopeer2-server gives following output [INF]: SR: Published event “rpc” “/ietf-netconf:edit-config” with ID 1 priority 0 for 1 subscribers. [INF]: SR: Processing “/ietf-netconf:edit-config” “rpc” event with ID 1 priority 0 (remaining 1 subscribers). [INF]: NP: edit-config error-option “stop-on-error” not supported, rollback-on-error will be performed. [INF]: SR: Successful processing of “rpc” event with ID 1 priority 0 (remaining 0 subscribers). [INF]: SR: Event “rpc” with ID 1 priority 0 succeeded. [INF]: NP: Session 1: thread 3 event new RPC.

I am not able to understand why netopeer2-serever not calling my registered callback function

here are my edit config file logs

xmlns= "urn:sysrepo:my"
<turned-on>1</turned-on>

Kindly help
