How to use my .mo file in the Divi child theme instead of file in a parent /builder directory?

its because there was different domain! I added another load_theme_textdomain and it works now.

function my_lang_function() {
     load_theme_textdomain( "Divi", get_stylesheet_directory() . "/lang" );
     load_theme_textdomain( "et_builder", get_stylesheet_directory() . "/lang/builder" );
}        
add_action( "after_setup_theme", "my_lang_function" );

its my code in function.php of child-theme.
is anything wrong with this code?
