How to use ' and " in the KendoCombobox / Grid Edit

[Bart]

I want to use ' in the text field of the category in this demo: http://demos.kendoui.com/web/grid/foreignkeycolumn.html

But, when I use this character it breaks and will not show any grid at all. Escaping it with \ or using the ascii code did not work at all for me.

Does anyone have some insight on this?

Cheers
