Hi srinath4ever,
If you watch the source object, then whenever you update anything in that source object, the Grid’s source property will be set again so I suggest you to use jqx-watch only when it is necessary and only for very specific properties, not for hierarchy of properties, because if you watch for a hierarchy, then any change in a property or sub property or a sub sub property will require an update of the widget which will affect its performance. I also suggest you to write your future topics about AngularJS in the Forum about AngularJS, not in General Discussions.
Best Regards,
