Hello Jean,
Thank you for the repro demo. Currently, setting array of objects directly to the widget is not supported. Basically, the value of the k-ng-model is directly passed to the value method of the widget, which accepts only an array of primitive values. We will further consider how this scenario should be supported.
For now you will need to use primitive values only.
Regards,
