RadiobuttonFor is not working for property inside a colletion (ASP.Net MVC3)

My view model looks like :

public class ShippingInfo
 {
     public string DiagID { get; set; }
 
     public Collection<AddressInfo> AddressSuggestions { get; set; }
 }
 
 
 public class AddressInfo
 {
     public int ID { get; set; }
     public string CompleteAddressInfo { get; set; }
 }
 

When I am trying to bind the radio button in my view, its not rendering.

    @if (Model.AddressSuggestions != null)
     {
         for (int i = 0; i < Model.AddressSuggestions.Count; i++)
         {
             Html.RadioButtonFor(m => m.AddressSuggestions[i].CompleteAddressInfo, Model.AddressSuggestions[i].CompleteAddressInfo, false);
         }
     }
 

I am expecting my radio button selection should persist in the Model when I am posting the form (Model Binding). I would appreciate if anyone points out the problem in my code.
