Post null no Edit MVC

Question

Hey, I got this situation, man Edit returns a group of Classes filled for editing. In my View the data is filled correctly, however, when I edit a field and have it saved in the Edit (Post) my Model zero arrives, that is to say, NULL. I’ve already found out it’s because of Partial, have some other way for me to accomplish?

below follows my code:

CONTROLLER (GET)

    public ActionResult Edit(int? id)
    {
        if (id == null)
        {
            return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
        }

        var cadastro = new Cadastro(); // Inicializa o Grupo de Classes...

        cadastro.Pessoa = new Pessoa();
        cadastro.Fisica = new Fisica();
        cadastro.Juridica = new Juridica();

        cadastro.Pessoa = db.Pessoas.Find(id);

        if (cadastro.Pessoa == null)
        {
            return HttpNotFound();
        }

        if (cadastro.Pessoa.Tipo == "F")
        {
            cadastro.Fisica = db.Fisicas.Find(id);
        }
        else
        if (cadastro.Pessoa.Tipo == "J")
        {
            cadastro.Juridica = db.Juridicas.Find(id);
        }

        return View(cadastro);
    }

VIEW EDIT

@model CodeFirst.Models.Cadastro

@using (Html.BeginForm())
{

@Html.AntiForgeryToken()

<div class="form-horizontal">
    <div class="form-horizontal">

        @Html.HiddenFor(model => Model.Fisica.IdPessoa)
        @Html.HiddenFor(model => Model.Juridica.IdPessoa)

        @if (Model.Pessoa.Tipo == "F") {
            <p>Pessoa Fisica:</p>
            <input type="radio" name="radio" value="F" checked="checked" class="radio">
            <input type="radio" name="radio" value="J" class="radio">
            <script> $('.boxf').show(); </script>
        } else
        if (Model.Pessoa.Tipo == "J")
        {
           <p>Pessoa Juridica:</p>
            <input type="radio" name="radio" value="F" class="radio">
            <input type="radio" name="radio" value="J" checked="checked" class="radio">
            <script> $('.boxf').show(); </script>
        }

        @Html.LabelFor(model => model.Pessoa.Documento)
        @Html.EditorFor(model => model.Pessoa.Documento)

        <div class="boxf">
            @Html.Partial("~/Views/Shared/EditorTemplates/_PessoaFisica.cshtml", Model.Fisica)
        </div>

        <div class="boxj">
            @Html.Partial("~/Views/Shared/EditorTemplates/_PessoaJuridica.cshtml", Model.Juridica)
        </div>
        <div class="row marginCimaBaixo text-right">
             <input type="submit" class="btn btn-success" value="Salvar Cadastro"   />
        </div>
    </div>
   </div>  
}

CONTROLLER (POST), HERE THE REGISTRATION ARRIVES NULL !

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Edit(Cadastro cadastro)
    {
    }

REGISTER CLASS

public class Cadastro
{
    public Pessoa Pessoa { get; set; }
    public Fisica Fisica { get; set; }
    public Juridica Juridica { get; set; }
}

SOLUTION

Very simple solution, my EditorTemplates has to be the same name as mine Class

instead of using

@Html.Partial("~/Views/Shared/EditorTemplates/_PessoaFisica.cshtml", Model.Fisica)

use:

@Html.EditorFor(model => Model.Fisica)
