Line item link action is not responding in our custom powl query

Sap e-recruitment powl query result line item link to action is not responding

Hi Experts,

We are trying to create a custom query from standard query in SAP E-recruitment dash board , but when we click on query result line item, it is not resonding..We completed all the configurations  and created a component configuration and application configuration in POWL_UI_COMP. When we tested from SE80 and also from portal , it is not responding. We did debugging in the feeder class and it is triggering all feeder class ,but not displaying the results.

please advise.
