            .Name("ComboPais")
            .SelectedIndex(-1)
            .BindTo(new SelectList(Model.combopais.Paises, "ID", "NombrePais"))
            .ClientEvents(events => events.OnChange("onPaisChange"))
            )

        public ActionResult NuevoClienteNacional()
        {
            model.combopais.Paises = dbPais.Pais.ToList();
            return View(model);
        }

Class

namespace SACC.Models.Forms
{
    public class IngresoClienteNacional
    {
        public Cliente  cliente { get; set; }
        public ComboBoxPais combopais { get; set; }

        public IngresoClienteNacional()
        {
            cliente = new Cliente();
            combopais = new ComboBoxPais();
        }
    }

    public class ComboBoxPais
    {
        public ComboBoxPais()
        {
            Paises = new List<Pais>();
        }
        public IEnumerable<Pais> Paises
