Adding custom fields in Create Application Group Web dynpro

I have to add fields in "Create Application Group". I have add the fields successfully in Customize include of HRP5125.

I have also successfully add the pre exit in the context controller method "save_appl_grp".

In all the structures the values are also coming like the following structures.

RCF_S_APPL_GROUP_INFO_TEXT

RCF_S_APPL_GRP_INFO_UI

WD_ASSIST->GS_BASIC_INFO

LS_GRPLIST_BASIC_INFO

But still when it pass the function "Save_appl_grp" my customize fields becomes empty in structure "gs_appl_group_info" and data do not saved.

Any help much appreciated.
