Changing order of TabularInline items not working

[tyctor]

DjangoSuit v2
Django 2.2.6

after changing order of TabularInline items, sended values of input sort_order remains same
so new order is not saved
is here somebody with same issue?

ok i found what it is not working but i am not sure why...
problem is in suit.sortables.js on line var selector = $(this).selector;
where variable selector is undefined, so it causes that new order is not submited
@darklow can you confirm this for me and advise what could be problem?

now i can see important difference between demo and my app
i am using Django 2.2, which contains jQuery 3.3
so probably that is source of all my problems
$(this).selector is not supported from jQuery 3.0
