ASP.NET Web API deep model binding

问题

I've noticed (even in Web API 2.1) that deep parameter types get filled (processed by the model binder) only on the first level. That is :

public class Person
{
    public string Name { get; set; }
    public PersonDetails Details { get; set; }
}

public class PersonDetails
{
    public string Address { get; set; }
    public int Age { get; set; }
}

// ...

public class PersonController : ApiController
{

    [HttpPost]
    public void ProcessPerson(Person person)
    {
        // person.Name is filled in correctly
        // person.Details.Address and person.Details.Age are not filled in correctly. That is, they have default values (null and 0)
    }
}

Is there a simple solution for this problem, except flatting out the Person class like so ?

public class PersonData
{
    public string Name { get; set; }
    public string Address { get; set; }
    public int Age { get; set; }   
}

Later edit 1 :

1. If I flatten the Person class I get all the data correctly
2. The request is made by POST (and not GET) because I need to ensure there is no caching and since the operation alters state it would be semantically incorrect to use GET
