SQL UPDATE from PL/SQL triggered by button

Question

I have a form with the normal buttons (create/save/delete) working.
For 2 of the fields I want to introduce a calculation on demand system. What I did is: created a button compute and associated some PL/SQL with it. The button submits as "compute" (something I made up) and has a branch that goes back to the same page. The button's PLSQL code is the following process (After Submit):
DECLARE
  rasaDom VARCHAR2(2);
  pRasaDom NUMBER;
BEGIN
tRace(:APP_SESSION, to_number(:P5_K));
domRace(:APP_SESSION, rasaDom, pRasaDom);
if (pRasaDom > 0 and pRasaDom <= 100) then
     :P5_RASADOM := rasaDom;
     :P5_PRASADOM := pRasaDom;
     update BOVIS.S_CIV_F SET RASADOM=rasaDom, PRASADOM=pRasaDom where K = to_number(:P5_K);
     commit;
     wwv_flow.debug('THEN! rasaDom=' || rasaDom || ' %=' || pRasaDom);
end if;
END;
The problem is the the above UPDATE simply does not work!
I should also mention that:
- the normal update process does not run (which is fine), because:
0.03: ...Do not run process "Apply MRU", process point=AFTER_SUBMIT, condition type=REQUEST_IN_CONDITION, when button pressed=
- my process displays the success message
- the "then" debug message shows just fine.
It looks like the is a big rollback somewhere (this is why I added the commit there). My guess is that APEX is doing an update to the old value. What am I doing wrong?
Thanks!

Hello:
update BOVIS.S_CIV_F SET RASADOM=rasaDom, PRASADOM=pRasaDom where K = to_number(:P5_K);Your update statement is updating the columns back to their current values !
If you want the rasaDom and prasadom updated to what is contained in p5_rasadom & p5_prasadom your code should be
     update BOVIS.S_CIV_F SET RASADOM=:P5_RASADOM , PRASADOM=:P5_PRASADOM  where K = to_number(:P5_K);
