If you bring this demo into the Dojo, it does work.
If you compare the differences between the one that does work and the one that doesn't,
you will see that the non-working one includes
and the working one includes
So, there is some bug when using jquery 1.9.1.
Just change your dojo to use the one that comes with kendo and it should start working. I guess the doc site it configured to initialize the dojo differently than the demo site.
