Redirect to custom page after check-in

We have a profiled page in WCC. We have added a custom button (check-in & send) apart from the standard check-in button available. Requirement is to redirect to a different page than the check-in confirmation page called by default.

We have already tried adding a custom service with the redirect page & calling it on click of Check-in & send but it fails(the values are somehow being cleared). So, we are now calling the standard check-in service on click of both buttons but need to redirect to different page depending on the button clicked by user.

Any pointers are appreciated.

Thanks
