How to pass a model containing IEnumerable model (complex) to a controller from a C # MVC3 view?

I looked at other questions and answers on this site, but I can not find the answer that I need.

I have a StudentRecord object:

public class StudentRecord : Persistent {
        public virtual string LastName { get; set; }
        public virtual string FirstName { get; set; }
        public virtual DateTime Dob { get; set; }
        public virtual int StudentRef { get; set; }
        public virtual IEnumerable<StudentAddress> Addresses { get; set; }
        public virtual StudentAddress Address { get; set; }
        public virtual string Notes { get; set; }
    }

As you can see, it contains a single StudentAddress object, as well as an IEnumerable from StudentAddress:

public class StudentAddress: Persistent {
        public virtual int StudentRef { get; set; }
        public virtual string Addressee { get; set; }
        public virtual string Property { get; set; }
        public virtual string District { get; set; }
        public virtual string PostalTown { get; set; }
        public virtual string County { get; set; }
        public virtual string Postcode { get; set; }
    }

I pass the student record to the view contained within the viewmodel:

public class UserViewModel {
        public StudentRecord Student;      
        public ICurrentUserService CurrentUserService;
        public ParentUser ParentUser;        
    }

Then display it on the form so that it can be edited, and submitting the form passes StudentRecord back to the controller. Everything works fine, except for Addresses in StudentRecord, are null. The only StudentAddress in StudentRecord is if a new address is added, and that works fine too.
