How popular is a select with JQuery, JSON and AJAX? (MVC)

I followed some codes that I found here on how to populate a selectbox, but it is not working, is something missing? I'm getting a list of data with my Controller.

JavaScript

$(document).ready(function () {
        $(document).select(function () {
            $.ajax({
                type: 'POST',
                url: "/Empresas/SelecionarEmpresas",
                data: { empresa: $("#empresa").val() },
                dataType: "json",
                success: function (json) {
                    var options = $('#empresa');
                    options.find('option').remove();
                    $.each(json, function (key, value) {
                                 $('<option').val(value.IdEmpresa).text(value.Nome).appendTo(options);
                        //options += '<option value="' + key + '">' + value + '</option>';
                    });   
                }
            });
        });
    });

View

<div class="form-group">
            <label class="col-md-2 control-label">Empresa: </label>
            <div class="col-md-6">
                <select class="form-control" name="empresa" id="empresa"></select>
            </div>
        </div>

Controller

public class EmpresasController : Controller
    {
        public ActionResult Empresas()
        {
            return View();
        }

        [HttpGet]
        public JsonResult SelecionarEmpresas()
        {
            EmpresaBLL bll = new EmpresaBLL();
            List lista = bll.SelecionarEmpresa();

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

BLL

public class EmpresaBLL
    {
        public List SelecionarEmpresa()
        {
            EmpresaDAL dal = new EmpresaDAL();
            DataTable dt = dal.SelecionarEmpresa();

            List ListaDeEmpresa = new List();
            foreach (DataRow dr in dt.Rows)
            {
                EmpresaModel emp = new EmpresaModel
                {
                    IdEmpresa = Convert.ToInt32(dr["IDEMPRESA"]),
                    Nome = dr["NOME"].ToString(),
                    LogoPath = dr["LOGPATH"].ToString()                                
                };
                ListaDeEmpresa.Add(emp);
            }
            return ListaDeEmpresa;
        }

Model

public class EmpresaModel
    {
        public int IdEmpresa { get; set; }
        public string Nome { get; set; }
        public string LogoPath { get; set; }
    }
