$("#scheduler").data('kendoScheduler') is undefined

Hello Asif,

Please take a look at this Kendo UI Dojo by Progress which illustrates how to make a reference to a Kendo Scheduler.

Also, please take a look at this documentation pertaining to widgets unavailable or undefined.  Make sure there are not multiple script reference to jQuery.  

Hope this clears things.
