How to save data and to add new tag and its data f

I followed a tutorial on making a multiple select tag mode in this link http://jsfiddle.net/dplanella/N6bQE/36/.

PROBLEM:

If I choose some value from the multiple select, how can I check if the I already select the data from the multiple select to be not shown once I open the multiple select again just like the link performed above?
~~How can I update the values to the database once I finish chose value/s from the multiple select just like the link performed above?~~ DONE
Add new tag/s even the tag/s text are not in the source data (i.e: http://jsfiddle.net/dplanella/N6bQE/36/)

CONCEPT/GOAL:

To make a trello-like labels assigned at the selected tickets/tasks
~~make it updated at the once performed edit/choice of selection in the multiple select field~~ DONE!
~~Can delete labels and update the db~~ DONE!: Store the data via data ID when update or delete in this form: "1,2"

I've implemented those codes with CodeIgniter 3.0 HMVC, jQuery, and a Slim Framework API for getting data. Apologies for the arrangements of codes and the grammar.

**[UPDATE]: ** I tried to implement this in jsfiddle and I apply my codes and the link I based above. And the result at this jsfiddle is the output what I am trying to achieve. More of my concern/problem are stated below and i update the javascript code:
