i m using this plugin in my nodejs+coffeescript+jqury app. the plugin displayed fine, but when i selected multi level values, it returned value as empty string. when i select only one level value, it can return the value correctly.

Hey @uhdyi! I've just had this repo transferred back to me from my previous employer (I originally created it while working there). Over the coming days and weeks I'll be catching up with all the issues and looking into personally maintaining this in the long run.

Sorry that your comment has gone un-replied for so long, but now it's back in my hands I'll try my best to stay on top of it all.
