Problem while setting the property of column in ALV

Question

Hi ,
I have created a alv dynamically and setting the properties of the column like column header text but its not getting updated .
see the below code for ref.
lr_column_settings ?= lr_config_table.
  data:
    lt_columns type salv_wd_t_column_ref.
  lt_columns = lr_column_settings->get_columns( ).
  data: lr_column      type ref to cl_salv_wd_column,
    lr_header      type ref to cl_salv_wd_column_header,
    ls_column type salv_wd_s_column_ref.
  loop at lt_columns into ls_column.
    case ls_column-id.
      when 'MOIST'.
        lr_column = ls_column-r_column.
    lr_header = lr_column->get_header( ).
    lr_header->set_text( 'Moisture %' ).
I am able to set the alv properties like  visible row count etc ..
can anybody help out in this issue

I was just able to change my headers with the following:
data:
    lt_columns     type salv_wd_t_column_ref,
    ls_column      type salv_wd_s_column_ref,
    lr_header      type ref to cl_salv_wd_column_header.
  lt_columns = lo_value->if_salv_wd_column_settings~get_columns( ).
  loop at lt_columns into ls_column.
    lr_column = ls_column-r_column.
    lr_header = lr_column->get_header( ).
    lr_header->set_ddic_binding_field( if_salv_wd_c_column_settings=>ddic_bind_title ).
    lr_header = lr_column->create_header( ).
    case ls_column-id.
      when 'CNT_LINEITEMS'.
        lr_column->r_header->set_text( 'Line Items' ).
      when 'VAL_OPEN'.
        lr_column->r_header->set_text( 'Open Amount' ).
      when others.
    endcase.
endloop
