        public ActionResult Index()
        {
            return View();

            ViewBag.cpf = cpf;

The submit will send all information that is within form , and notice that in your code the submit is outside the form that contains the fields. I suggest putting your fields as in the following example:

 @using (Html.BeginForm("RetornoObjetoPorCpf", "LocalizarController", FormMethod.Post))
{
            @Html.LabelFor(model => model.cpf, htmlAttributes: new {@class = "control-label col-md-2"})
            <div class="col-md-10">
                @Html.EditorFor(model => model.cpf, new {htmlAttributes = new {@class = "form-control"}})
                @Html.ValidationMessageFor(model => model.cpf, "", new {@class = "text-danger"})
            </div>

            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="Buscar" class="btn btn-default"/>
            </div>
}
