Date is coming in wrong format

In a jquery function, I get a date in my View. It turns out the date is coming like this:

/Date(1402369200000)/

I know I need to cast or something, but I do not know how. Can someone give me a help? My controller:

[HttpPost]
        public JsonResult MontaAgendamento(Agendamentos _agendamento)
        {
            V99_WEBEntities db = new V99_WEBEntities();

            var agendamento = (
                             from pdv in db.T_PDV
                             from tarefa in db.T_TarefaParceiro.Where(trf => trf.CNPJ == pdv.CNPJ).DefaultIfEmpty()
                             from parceiro in db.T_OsParceiro.Where(prf => prf.IDTarefaParceiro == tarefa.IDTarefaParceiro)
                             from acao in db.T_Acao.Where(ac => ac.IDAcao == tarefa.IDAcao).DefaultIfEmpty()
                             from proxima in db.T_ProximaAcao.Where(pxm => pxm.IDAcao == acao.IDAcao).DefaultIfEmpty()
                             from info in db.T_InfoClientePdv.Where(inf => inf.CNPJ == pdv.CNPJ).DefaultIfEmpty()
                             from cliente in db.T_Cliente.Where(clie => clie.IDCliente == info.IDCliente).DefaultIfEmpty()

                             where pdv.CNPJ == _agendamento.Cnpj

                             orderby parceiro.DataVisita descending

                             select new
                             {
                                 pdv.CNPJ,
                                 pdv.DataCadastro,
                                 cliente.RazaoSocial,
                                 acao.Acao,
                                 proxima.ProximaAcao,
                                 parceiro.IDOsParceiro,
                                 parceiro.NumOs,
                                 parceiro.DataVisita,
                                 parceiro.DataAgendamento,
                                 parceiro.Tecnico
                             }).ToList().FirstOrDefault();

            return Json(new { agendamento }, JsonRequestBehavior.AllowGet);
        }

My jquery:

function MontaAgendamento() {

    var str = "";
    var resultado = jQuery.parseJSON('{ "Cnpj": "' + $("#txtCNPJ").val() + '" , "Os": "' + $("#txtOS").val() + '" , "Acao": "' + $("#txtAcao").val()
                                        + '" , "ProximaAcao": "' + $("#txtProxAcao").val() + '" , "DataCadastro": "' + $("#txtDataCadastro").val() + '" }');

    var _agenda = $('#txtCNPJ').val() + $("#txtOS").val();

    $.ajax({

        url: '/GerenciarPDV/MontaAgendamento',
        dataType: "json",
        contentType: "application/json; charset=utf-8",
        type: "POST",
        data: JSON.stringify({ _agendamento: resultado}),
        success: function (data) {
