Because your website is loading jQuery1.6, but
.on() function has been introduced with jQuery1.7 (more info:
api.jquery.com/on/)
To fix it;
1- Install jQueryEasy plugin. See this topic for more info and to get the download link:

2- Choose jQuery1.7 from the plugin parameters and publish the plugin.
3- DONE!
The jQuery conflict problem should be gone.
