bind attribute include and exclude property with complex type nested objects

Ok, this is weird. I cannot use BindAttribute's Include and Exclude properties with complex type nested objects on ASP.NET MVC.

Here is what I did:

Model:

public class FooViewModel {

    public Enquiry Enquiry { get; set; }
}

public class Enquiry {

    public int EnquiryId { get; set; }
    public string Latitude { get; set; }
}

HTTP POST action:

[ActionName("Foo"), HttpPost]
public ActionResult Foo_post(
    [Bind(Include = "Enquiry.EnquiryId")]
    FooViewModel foo) {

    return View(foo);
}

View:

@using (Html.BeginForm()) {

    @Html.TextBoxFor(m => m.Enquiry.EnquiryId)
    @Html.TextBoxFor(m => m.Enquiry.Latitude)

    <input type="submit" value="push" />
}

Does not work at all. Can I only make this work if I define the BindAttribute for Enquiry class as it is stated here:

How do I use the [Bind(Include="")] attribute on complex nested objects?
