I have tried for almost 10 hours straight and cannot find the answer.
Everything is working except where I want to change data in the a Dropfown based on a selection in another dropdown
When I create og Edit data

This single line of code is the reason to my frystrations
editor.field('projects_rss.feed_category_id').update(obj);

this is my client side code

var editor;

$(document).ready(function() {


    editor = new $.fn.dataTable.Editor( {
