UpdateModel will not update

The UpdateModel command does not update my object. The code is executed with no changes. Can you see why?
I think the problem is the name of the prefix. I have tried changing it; "Contract", "Contracts" and "contract".

The controller;
        [Authorize(Roles = "Inputter")]
        [HttpPost]
        public ActionResult Edit(int contractId, FormCollection formValues)
        {
            if (ModelState.IsValid)
            {
                using (var db = new ITOCEntities())
                {
                    var contract = db.Contracts.Single(x => x.ContractId == contractId);
                    string letter = contract.ContractNo_Letter;

                    UpdateModel(contract, "Contracts", formValues);
                    if (contract.ContractNo_Letter != letter)
                        contract.ContractNo_Number = Contract.AutogenerateContractNumber(contract.ContractNo_Letter);

                    var clientContact = db.Contacts.Single(x => x.ContactId == contract.ClientContactId);
                    UpdateModel(clientContact, "Contact", formValues);
                    var contractAdministrationContact = 
                        db.Contacts.Single(x => x.ContactId == contract.ContractAdministratorContactId);
                    UpdateModel(contractAdministrationContact, "Contact", formValues);
                    db.SaveChanges();
                }

                return RedirectToAction("List");
            }
            return View();
        }
------------------------------------------------------------
The ViewModel

    public class ContractViewModel
    {
        //private ITOCEntities db = new ITOCEntities();
        public Contract contract { get; set; }
        public IList<ContractType> contractTypes { get; set; }
        public IEnumerable<SelectListItem> contractTypesSelectList
        {
            get
            {
                return this.contractTypes.Select(item => new SelectListItem
                {
                    Text = item.ContractType1,
                    Value = item.ContractTypeId.ToString()
                });
            }
        }

 
        public Contact clientContact { get; set; }
        public Contact contractAdministratorContact { get; set; }

        public ContractViewModel()
        {
            using (var db = new ITOCEntities())
            {
                this.contractTypes = db.ContractTypes.ToList();

                this.clientContact = new Contact();
                this.contractAdministratorContact = new Contact();
                this.clientContact.ContactTypeId =
                    db.ContactTypes.Where(x => x.ContactType1 == "Client").SingleOrDefault().ContactTypeId;
                this.contractAdministratorContact.ContactTypeId =
                    db.ContactTypes.Where(x => x.ContactType1 == "CA").SingleOrDefault().ContactTypeId;
            }
        }
        public ContractViewModel(int contractId)
        {
            using (var db = new ITOCEntities())
            {
                this.contractTypes = db.ContractTypes.ToList();
                this.contract = db.Contracts.Where(x => x.ContractId == contractId).SingleOrDefault();
                this.clientContact = 
                    db.Contacts.Where(x => x.ContactId == this.contract.ClientContactId).SingleOrDefault();
                this.contractAdministratorContact =
                    db.Contacts.Where(x => x.ContactId == this.contract.ContractAdministratorContactId).SingleOrDefault(); 
          
            }
        }

The ViewModel reference in the view;

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" 
    Inherits="System.Web.Mvc.ViewPage<ITOC.WebUI.Models.ContractViewModel>" %>

- UpdateModel usually doesn't working properly, may be you HTML form contains check box, combo box...etc, it only work well when the form controls are all text box, better don't use UpdateModel, try to set contract data manually
