Dropdown not allowing to select on new rows

[fumeeptc]

Hey there!
Why this https://jsfiddle.net/master1991/b6ozq0u0/ works here

but does not works in my code? In my code data is loaded via PHP while loop.
The main function work add, remove but select is not allowing to select in new fields .

What could cause this? Also should i load select dynamicly instead using ajax? (need also for each line to select box not repeat!)

Any solutions or guess?

I managed to make it work with this https://jsfiddle.net/master1991/mkey6h2o/

no the only thing i need is to not allow pick the same value in all of the dropdowns!

This one is done:
Pluss i need to limit add to dropdown value count!
with: var length = $(\'#mySelectList > option\').length;
