Absent for a year, plugin no longer works

[rektangle]

So, a year back I was working on a plugin for a custom combat system. It was working pretty neatly, I might say, though perhaps it was a bit too ambitious and I was never able to get it fully where I wanted.

I am looking to revive my old forum where I used this, but while it used to work, it... does nothing now. I know a few of its quirks but this was not one of them.

Basically, the plugin creates a button, which, when pressed, would give a prompt with some fields the user could fill out. After that, it would be saved in a key, and you could use another button to go to a new page to interact with the thing that was created by you filling the prompt. It was basically for a very simple battle system, where you could create encounters with some rules. 

The issue is, when pressed, the button does not prompt anything. No error code is given, and I cannot find the faulty line. Oddly enough, the other code, the one to create a new page and all that seems to work. 

I've been tinkering around a bit, but so far, no luck.

I should add, self-taught to code by basically ramming my head into documentation, so I will admit to be very green and am very likely to have caused this myself sometime last year while still developing. I've seldomly touched coding in the last year, so, I actually think I forgot a lot :')

Anyway, here's my test forum where the buttons can be found.

And here's the code that (I think, to be fair I didn't comment many of the lines) makes the button "work"


           createBattle: function(){

               var self = this;

               var button = $("<button>Create Battle</button>").click(function(){

                   var thread = parseInt(pb.data("route").params.thread_id, 10);

                   battleData.BattlID = thread;

                   battleindex.set({value: battleData});

                   self.askforReg();

               });

               var container = $("<div/>").append(button).css({

                   "text-align": "center",

                   "margin-bottom": "5px"

               });

               $("#content").prepend(container);

           },


"battleindex" is a variable that I use to quickly access the key, battleData is an object with the values I need.
