Hello Federico,

Based on the provided code, I believe the reason for this behavior is the incorrect syntax.

Having said that, please check the MVVM demo of the Grid:

• http://demos.telerik.com/kendo-ui/grid/mvvm

In the above demo, see how the events are handled with the usage of the data-bind object attribute.

I hope this helps.

Hello Neeraj,

I am afraid that I do not understand your project requirements. Having said that, could you please elaborate on them?

I look forward to hearing from you.
