Jquery on click stopped working.

I have a Coldfusion page that uses jquery on click.  It has stopped working and I have no idea why.  No changes were made to the code.  I have upgraded the site to use 1.11 and it still doesn't work.  Dev tools shows no errors.  I can set a breakpoint but it never hit's that line.  I also have 2 on change functions that also don't work.  I think I need a little help debugging this one.  There is a $(document).ready(function () { at the top of the js.   I created a standalone page based on the code below and everything works.  Where do I begin?

EDIT: Actually I am getting an error; NS_ERROR_NOT_AVAILABLE:
