FIO-8724: Fixed firing change event for DataGrid component

Description

Issue: Any change to the data grid (e.g., adding or removing a row) or any change to a nested component within the data grid should trigger a data grid change event and refresh the select component based on the refresh on data grid configuration. Change events are only fired for the nested component itself, not for the entire data grid.

Solution: The Edit Grid component fires change events when a row is saved or removed. However, the Data Grid should be treated as a special case of the Edit Grid, where any change to a nested component triggers a row save. Therefore, we need to track change events in the data grid and fire an additional event for the entire data grid component. This will ensure that the select component can refer to the data grid for refreshing.
