Problem with autocomplete developing c-gtk app using Ycmd completion

[Viterzgir]

I installed ycmd completions plugin wim ycmd server and completions work fine , but whenever I
need also autocomplete for gtk apps I have no completion suggestions for gtk identifiers.
my ycm_extra_conf.py file has all the includes for gtk headers as well as others.Ycmd show output
[YCMD] #### START COMPLETION ####
