复杂对象的隐藏字段未传递给控制器

Question

I am using the HTML helper HiddenFor inside of a for loop to bind some properties of a complex object back to my model.

If I interrogate the view, I can see the values are being set correct in the hidden fields, but when I submit my form, the values are null in the controller.

VIEW

 @for (int i = 0; i < Model.CustomerSearchResponses.customers.Count; i++)
 {
     @Html.HiddenFor(m => m.CustomerSearchResponses.customers[i].name.first)
     @Html.HiddenFor(m => m.CustomerSearchResponses.customers[i].name.last)
     @Html.HiddenFor(m => m.CustomerSearchResponses.customers[i].name.company)
     @Html.HiddenFor(m => m.CustomerSearchResponses.customers[i].address.line1)
     @Html.HiddenFor(m => m.CustomerSearchResponses.customers[i].address.line2)
     @Html.HiddenFor(m => m.CustomerSearchResponses.customers[i].address.city)
     @Html.HiddenFor(m => m.CustomerSearchResponses.customers[i].address.stateProvince)
     @Html.HiddenFor(m => m.CustomerSearchResponses.customers[i].address.postalCode)
     @Html.HiddenFor(m => m.CustomerSearchResponses.customers[i].address.country)
  }

<input id="CustomerSearchResponses_customers_0__name_first" name="CustomerSearchResponses.customers[0].name.first" type="hidden" value="BRIAN">

MODEL

    public class RequestViewModel
{
    **some other props**
    public CustomerSearchResponse CustomerSearchResponses { get; set; }
}

CONTROLLER

[HttpPost]
public ActionResult QASAddress(RequestViewModel model, string previousButton, string submitButton)
{
// Do Stuff 
}

Hidden Fields

Not all hidden fields are posted here for the sake of length, but they are all setting correctly. When I POST my form, the CustomerSearchResponses.customers[i] object is there, but the name and address objects are null.

I created a sample application with GET and POST actions in a controller and I see customer properties in POST as shown below:
