Returns value for an Action

I have a form with the following input.

<div class="form-group"> 
<label class="control-label col-md-2" for="nome">Logradouro</label> 
<div class="col-md-10"> @Html.EditorFor(model => model.endereco.Logradouro, new { htmlAttributes = new { @class = "form-control", required = "required" } }) @Html.ValidationMessageFor(model => model.endereco.Logradouro, "", new { @class = "text-danger" }) 
</div> 
</div>

But when my action is triggered the value is not set in my model

@model Model.Empresa

My Action

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Empresa(Empresa empresa)
    {
        new EmpresaBO().Inserir(empresa);
        new EnderecoBO().Inserir(empresa.endereco, empresa.Cnpj);

        return RedirectToAction("Home", "Dashboard", new { area = "" });
    }

My class

public class Empresa
{
private string razaoSocial;
private string contato;
private bool ativa;
private string naturezaJuri;
private string nomeFan;
private string cnpj;
public Departamento departamentos;
public Endereco endereco;
public Administrador administrador;
}

Only values that are primitive within my class are returned to my action, how can I resolve this?
