Checking internationalize

I am translating my theme to check translatable feature works or not.

but I couldnt find a proof that the feature setted ok.

I used poedit program.I selected my theme folder then it gave me .po and .mo files.

I changed some words from its editor to check.

I pasted the files into my theme under languages folder.

hekim-tr_TR.mo and hekim-tr_TR.po files.

hekim is my theme’s domain name.

I use redux framework for admin panel.I checked "helvatica themes" words but it didnt turned to "helvatica themes | turkish".

I added these line to my style.css under main folder:

Text Domain: hekim
    Domain Path: /languages
    License: Hekim License

but no result.

my theme main folder’s name is html5-blank.

what is my problem?
