You doubt about Ubmit and jquery?

Question

I am developing an application in Asp.Net MVC and I am having a problem that I am not able to solve. I have a form with 2 buttons submit, and when I do the submit I want to get the name of the button I clicked on id and thus alter a input text of the form. The problem is that before getting the name of this button the form is all sent and I can’t get the name of this button to change the value of input text. Soon after the form is submitted, I try to send again and finally I can get the id and change the value of the input text.

My question is: When I do the first Submit, it sends the whole form and does not take the id of the button and soh I can do it after processing ?

I’m trying to do it like this.

Jquery

$(document).ready(function () { 
    $('#addPropriedade').submit(function (e) {
        e.preventDefault();

        $('#gravarPublicar').click(function () {
            $('#status').val("1");
        });
        $('#gravar').click(function () {
            $('#status').val("0");
        });
        var dados = new FormData($('#addPropriedade').get(0));



        $("#errorMessage").hide();
        var loading = $("#div_loading");
        $(document).ajaxStart(function () {
            loading.show();
        });
        $(document).ajaxStop(function () {
            loading.hide();
        });

        $.ajax({
            accepts: { json: 'application/json' },
            dataType: 'json',
            type: "POST",
            url: "/Propriedade/addAjax",
            data: dados,
            processData: false,
            contentType: false,
            success: function (data) {
                var status = data["status"];
                var msg = data["msg"];
                if (status === "1") {
                    $('#addPropriedade').trigger("reset");
                    $("#errorMessage").html(msg);
                    $("#errorMessage").prop("class", "alert-success");
                    //window.location.replace("/Empresa/view");                    
                } else {
                    $("#errorMessage").html(msg);
                    $("#errorMessage").prop("class", "alert-danger");
                }
                $("#errorMessage").show()
            },
            error: function (xhr, status) {
                $("#errorMessage").html("Erro tentando cadastrar");
                $("#errorMessage").prop("class", "alert-danger");
                $("#errorMessage").show()
            }
        });

        return false;
    });
});

Form

    @using (Html.BeginForm(null, null, FormMethod.Post, new { id = "addPropriedade", enctype = "multipart/form-data" }))
    {
        @Html.AntiForgeryToken()
        @Html.ValidationSummary(true)

        <!--Alterar o valor no submit -->
        @Html.HiddenFor(model => model.status);

<input type="submit" class="btn btn-success" value="Gravar e Publicar" id="gravarPublicar" name="gravarPublicar" />
 <input type="submit" class="btn btn-success" value="Gravar" id="gravar" name="gravar"/>
    }
