I've made a JQuery sortable accordion and have implemented a feature to add an additional level. I've but my brain to extensive work to create this and all appears to work, viewing source and whatnot to implement a new level, however upon doing so, the new level will not expand. I asked for help on Web Masters Stack Exchange posting this question, unfortunately it was put on hold as off-topic, but fortunately someone submitted an answer before this occurred.
The answer explains why it does not work and I should look into using AJAX to resolve, however I do not have a clue how to use AJAX and although I've been searching Google, I cannot find anything similar enough to help me enough to fix my website feature. I've created a JSFiddle of what I have done so far.
In addition to the above, but not so important; The "+ Add New" should look exactly the same as the accordion headers and behave the same way for hover.
I would be extremely grateful for some help to resolve as I have put my skills to the maximum to achieve what I've accomplished so far to create this small section of my website I'm working on for a charitable organisation.
