Check_Changed_Data not working

Question

Hi all,
In my BADI i am triggering an ALV grid pop-up to select values with check box. For getting the changed data i am using check_changed_data method. Even after selecting the check boxes in ALV pop i am not able to get the changed data.
program code :
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
    EXPORTING
      i_callback_program    = sy-repid
      i_grid_title          = 'Select MAil ID'
      is_layout             = lt_layout
      it_fieldcat           = t_fieldcat
      i_screen_start_column = 20
      i_screen_start_line   = 5
      i_screen_end_column   = 70
      i_screen_end_line     = 15
      I_SAVE                = 'A'
    TABLES
      t_outtab              = it_ZEMAIL
    EXCEPTIONS
      program_error         = 1
      OTHERS                = 2.
  IF sy-subrc <> 0.
  ENDIF.
data: gd_repid like sy-repid,
        ref_grid type ref to cl_gui_alv_grid.
  if ref_grid is initial.
    call function 'GET_GLOBALS_FROM_SLVC_FULLSCR'
      importing
        e_grid = ref_grid.
  endif.
  if not ref_grid is initial.
    call method ref_grid->check_changed_data .
  endif.
while debugging i found that the ref_grid remains initial after the function GET_GLOBALS_FROM_SLVC_FULLSCR.
so  call method ref_grid->check_changed_data  is not executed.
So how can i solve this problem.
Thanks in advance.
Venkat.

Hi,
u need to use user command
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
    EXPORTING
      i_callback_program    = sy-repid
      i_grid_title          = 'Select MAil ID'
     i_callback_user_command  = 'USER_COMMAND'
      is_layout             = lt_layout
      it_fieldcat           = t_fieldcat
      i_screen_start_column = 20
      i_screen_start_line   = 5
      i_screen_end_column   = 70
      i_screen_end_line     = 15
      I_SAVE                = 'A'
    TABLES
      t_outtab              = it_ZEMAIL
    EXCEPTIONS
      program_error         = 1
      OTHERS                = 2.
  IF sy-subrc  0.
  ENDIF.
FORM user_command USING lv_ucomm LIKE sy-ucomm
                  rs_selfield TYPE slis_selfield.
Declaration of local Variables
  DATA : lv_ref1 TYPE REF TO cl_gui_alv_grid.
Event
    WHEN <event>
      CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
        IMPORTING
          e_grid = lv_ref1.
      CALL METHOD lv_ref1->check_changed_data.
Now try this...
