title: Kendo Grid inside Jquery Dialog with modal Issue
body: <p>I have a kendo grid control inside jquery dialog. It works fine except when in dialog modal is true, I am not able to work on grid filter. If dialog modal is false, it works perfectly. It is must for me to apply modal true kind of functionality.</p>
