Kendo UI scheduler event editing returns wrong event

Hi, 

When I use e.preventDefault();  for editing by a condition based on event data, It returns wrong event data. Please check sample application and follow below steps to reproduce the error. 

1. Use google chrome and press Ctrl + Shift + I to get the console 

2. Click in Add Event button in the application and it will show events for the period. 

3. If you double click on an event and check event data such as start, end date, It always gives wrong data when you use e.preventDefault();

 Any idea how to solve this issue?

Thanks, 

Lilan
