Same behavior can be seen in Telerik's own online demo: http://demos.telerik.com/aspnet-ajax/grid/examples/overview/defaultcs.aspx
In Model column enter something like Joe's click the filter button, select Contains and you get:
Error: Expected ')'
Tried escaping the apostrophe as \' or /' or ['] - same result
As an unrelated issue - tried entering HTML encoded string version Joe's and clicked filter/Contains - page redirected to "Oh, no! It seems we've lost this page!"

This problem is already fixed in our Q1 2015 Beta release which is already available for download. You can test how the grid filtering is working with this version here:
Check out the Telerik Platform - the only platform that combines a rich set of UI tools with powerful cloud services to develop web, hybrid and native mobile apps.
I will report the bug as well.
