Thank you very much for the help. It have finally solved the problem.
BTW, one issue was left - the plus icon redirected to the creation
page instead of opening popup.
I've solved it by including the
<script type="text/javascript" src="/media/js/admin/
RelatedObjectLookups.js"></script>
directly in my template, but it's strange since my template extends
the "admin/change_form.html".
