Steps to reproduce:
1) Run attached test
Expected: test passes
Actually: test fails because Step 6 doesn't trigger onChange event. If you turn on Step 7 - the test will pass.
Telerik: we have implemented a new property InvokeOnChange for CheckBoxes and RadioButtons, which will be enabled by default while recording click events on those elements. For existing recorder tests the property should be changed manually in order to make it work. The new implementation will be available in our next internal product release planned second half of March 2014.
