FPM GAF Application refresh on button click.

Hello Experts,

I have a requirement in which I need to refresh my GAF application on button click. Currently I tried using bellow code but it did not worked .

wd_this->mr_fpm->raise_event_by_id( cl_fpm_event=>gc_event_refresh ).

According to my analysis this is GAF application and so it does not work.

Did anyone face the same problem .Help will be appreciated.
