     DATA events TYPE cntl_simple_events.

     APPEND event TO events.

     CALL METHOD oref->set_registered_events

i used the same method for refreshing but it just doesnt work.

When i first run the program for the first time, it brings the initial value to screen.

But after i enter input, the html page doesnt change. I cleared all of the objects and values but it just doesnt refresh.

Did you use this method CALL METHOD cl_gui_cfw=>dispatch.(Use this method to dispatch application events to the event handlers registered for the events. If you do not call the method within the PAI event of your application program, it is called automatically by the system after the PAI has been processed.)If not try using this method.
