Wonderful plugin but a little bug

I’ve use this plugin for years, but there is a bug I found:

In collapsFunctions.js, on the line 39 and line 51, Robert use the jQuery.live for click event, but the live function is removed on jQuery 1.9 [1], should use on function instead. If you do not include jquery-migrate, this plugin won’t work on collapse/expand

I’ve modified the collapsFunctions.js on my local, and hope this change will merge into n next version

before
`
./collapsFunctions.js:39: jQuery(‘#’ + id + ‘ span.expand’).live(‘click’, function() {
./collapsFunctions.js:51: jQuery(‘#’ + id + ‘ span.collapse’).live(‘click’, function() {
`
after
`
./collapsFunctions.js:39: jQuery( document ).on(‘click’, ‘#’ + id + ‘ span.expand’, function() {
./collapsFunctions.js:51: jQuery( document ).on(‘click’, ‘#’ + id + ‘ span.collapse’, function() {
`
