Populating custom fields on checkout page - php

Question

I have created two plugins:
To add 3 custom fields on register form
To add this 3 custom fields on checkout page and user dashboard panel.
I have successfuly added my fields in register form, checkout page and user dashboar panel but on checkout page I cannot populate them with the presaved values.
First plugin is for adding new fields in registration. The new fields are: 'billing_bulstat' ; 'billing_mol' and 'billing_adres'. They are succesfuly saved and displayed in user dashboard panel. The code is:

The second plugin adds three new custom field on checkout page. They are displayed, but are not automaticaly populated. I use $checkout->get_value( 'my_field_name' ) ); function, but is doesn't work.
I want they to be automatic populated with the presaved values. The fields are the same: 'billing_bulstat' ; 'billing_mol' and 'billing_adres'. The code is:
