How to save in database new order of nodes in tree with ajax | django?

Question

I use django-mptt application in backend and jsTree plugin in frontend to create such tree as in the picture below in my Django project:

jsTree plugin allows you to drag and drop nodes inside tree. django-mptt application by default in DB create fields like: tree_id, lft, rght and parent_id. tree_id field store information about order of nodes. parent_id field store information about ancestor.

When user click the button after drag and drop nodes I want to save the new order of items and there new dependencies (parent_id field) in database. Сan someone say me how to make such thing?

template:

{% load mptt_tags %}

<div id="documents">
<ul>
    {% recursetree documents %}
        <li data-id='{{ node.tree_id }}'>
            {{ node.title }}
            <ul class="children">
                {{ children }}
            </ul>
        </li>
    {% endrecursetree %}
</ul>
</div>

JS:

    $(function () {
        $('#documents').jstree({
            'plugins': ["wholerow", "dnd", "search"],
            'core': {
                'themes': {
                    'name': 'proton',
                    'responsive': true
                },
                "check_callback" : true
            },
        });
    });
