Re-freshing the detail form --- not so straightforward is it?

Question

hi there
this is my problem:
i have a master-detail form. Now this form basically provides the user the option to enter some parameters, which decides the number of rows to be entered in the detail.
master form: qty and starting serial number.
when he hits generate in master form, there are qty no. of records inserted in the detail table, but its not displayed in the detail form.
if i query the record, the updated detail form is shown.
so how can i make it so that when the user hits generate, the form detail part is automatically updated.
eg.
if the qty was 5 and thus there are 5 records(or serial nos.) in the detail, if he changes the qty to 8 and hits generate.. the detail block.. should update itself and show the 3 new records.
thanks

declare
     SERIAL_STRING VARCHAR2(50);
     trimmed_prefix varchar2(50);
     last_sr_no number(38);
     trav number(38);
     tab_ref number(10);
begin
     IF :mytable.TABLE_REFERENCE = -1 THEN
          select last_number into tab_ref from user_sequences where SEQUENCE_NAME = 'mytable_SEQ' ;
     ELSE
          tab_ref := :mytable.TABLE_REFERENCE;
          delete from mytable_updated GU where GU.table_reference = tab_ref;
     END IF;
     IF :mytable.VOUCHER_NO IS NULL OR
          :mytable.REF_NO IS NULL OR
               :mytable.USER_ID IS NULL OR
                    :mytable.QTY IS NULL OR
                         :mytable.PREFIX IS NULL OR
                              :mytable.START_# IS NULL
     THEN
          MESSAGE('ERROR:666746-ATOU : Please enter all the information');
     ELSE
               trimmed_prefix := RTRIM(LTRIM(:mytable.prefix));          
               last_sr_no := :mytable.start_# + :mytable.qty - 1;
               trav := :mytable.start_#;
               while trav <= last_sr_no loop
                    serial_string := trimmed_prefix || trav;
                    insert into mytable_updated values ( :mytable.voucher_no,:mytable.ref_no, :mytable.user_id, :mytable.item, 1, serial_string, tab_ref);
                    trav := trav + 1;
               end loop;
               :mytable.sr_updated := 'Y';                    
          :mytable.sr_no_start := trimmed_prefix || :mytable.start_#;
               :mytable.sr_no_end := trimmed_prefix || last_sr_no;
          do_key('commit_form');
          go_block('mytable_UPDATED');
          execute_query;
     END IF;          
end;
thanks for ur time in going throught this code..
do_key('commit_form');
          go_block('mytable_UPDATED');
          execute_query;
this bit... i save the changes and then go to the detail block as u suggested and execute query. it should update the records in the detail table... it works when i update the master record when i have do enter query . but when making new records... it does not work?
any idea why?
