Cell data not getting refreshed in which user enters data OO ALV(editable)

Question

Hi Friends,
I am using OO ALV for editable grid display.
I am unable to change grid data in the cell in which user enters something, using OO ALV. Did through debugging of my own program and found that some problem with system program. Then I did all system debugging. Could not find out why is the grid not getting refreshed with the new data in the cell in which user had entered some value. Rest of the cell's data are getting refreshed with the values which i am updating in the final internal table. I can see that the data in the final internal table is changed for the cell in which user enters data. But even after the call of
      CALL METHOD obj_alvgrid1->refresh_table_display
does not refreshes the data in the cell in which user had entered data. Rest of the cells data are getting refreshed.
Piece of code:
  SET HANDLER obj_event_receiver->handle_data_changed
                                     FOR obj_alvgrid1.
    METHODS: handle_data_changed
                   FOR EVENT data_changed OF cl_gui_alv_grid
                       IMPORTING er_data_changed
                                 e_onf4
                                 e_onf4_before
                                 e_onf4_after.
METHOD handle_data_changed.
  DATA : v_valid    TYPE char1,
         v_refresh  TYPE char1.
*--check mt_good_cells semantically
  CALL METHOD perform_semantic_checks( er_data_changed ).
*--If PBO is again visited, just refresh the ALV grid.
  CALL METHOD obj_alvgrid1->refresh_table_display
    EXCEPTIONS
      finished = 1
      OTHERS   = 2.
  IF sy-subrc <> 0.
    EXIT.
  ENDIF.
ENDMETHOD.
METHOD perform_semantic_checks.
    LOOP AT er_data_changed->mt_good_cells INTO w_good.
      v_index = sy-tabix.
      CASE w_good-fieldname.
        WHEN 'ZASCAS'.
*Now here based on some conditions I am changing my final internal table i_zamtsmatnp
                          MODIFY i_zamtsmatnp FROM w_zamtsmatnp INDEX
                                           w_good-row_id TRANSPORTING
                                             zascas modif.
User enters data in zascas field. Based on the data entered, I am changing other fields which is getting refreshed. I am also changing zascas in the program even after user had already entered the value which was bit wrong and i am correcting it in the program on the even "data_changed" even.
Please help me friends as i m strugling past hours wondering why the data is not getting refreshed for the cell in which user enter data.

Hi Surya,
   The approach you are following is correct. You need to use the comibnation of all these things:
Event - DATA_CHANGED
Methods - CHECK_CHANGED_DATA
             -  GET_CHANGED_DATA.
However, here are few standard programs which are having similar functionality.
BCALV_EDIT_03
BCALV_EDIT_07
Check out these once.
