It might be caused by the non-empty value for the "Id" property. The DataSource might think that the object is not "new" because it has a value for the "Id". Try removing the Id property from the object, or in the schema, set the defaultValue for the Id to "-1".

Indeed this is correct. The `Id` field is of type `number` and default value for numbers is `0`. However you are creating models with `Id` field initialized to `-1` and the model is not considered new.
You should either define defaultValue for the `Id` field in the model definition or skip setting `Id` field when creating new models.
