    Try:

    UpdateModel(viewmodel.Recipient, new[] { "MobileNumber" });

    Your problem is your using the string[] includes as view data expressions which would hypothetically hop around the object graph to model bind what you need.

    UpdateModel doesn’t work that way. Those strings are simply used as filters over properties.
