How to post updated form values to php?

Tried all possible ways: serialize(), val(). Can't get work autosubmit function. Form submission with button works well, each time it posts updated values but autosubmit function posts the last submitted with button values. How to post updated form values to php?

My JS looks like this

var autoSaveInterval = null;
var counter = 0;

function call() {
    var name = $("#name").val();
    var title = $("#title").val();
    var menu = $("#menu").val();
    var parentcheck = $(".parentcheck:checked").val();
    var id = $("#id").val开发者_JS百科();
    if (parentcheck == 0) {
        var parent = parentcheck;
    } else {
        var parent = $("#parent").val();
    }
    var content = $("#content").val();
    var dataString = 'name=' + name + '&title=' + title + '&menu=' + menu + '&parentcheck=' + parentcheck + '&id=' + id + '&parent=' + parent + '&content=' + content;
    postViaAjax(true, dataString)
}

function postViaAjax(autosaveMode, dataString) {

    $.ajax({
        type: "POST",
        url: "processor/dbadd.php",
        data: dataString,
        dataType: "json",
        success: function (result, status, xResponse) {
            var message = result.msg;
            var err = result.err;
            var now = new Date();
            if (message != null) {
                if (autosaveMode) {
                    $('#submit_btn').attr({
                        'value': 'Yadda saxlanıldı ' + now.getHours() + ':' + now.getMinutes() + ':' + now.getSeconds()

                } else {
                    $.notifyBar({
                        cls: "success",
                        html: message + ' ' + now.getHours() + ':' + now.getMinutes() + ':' + now.getSeconds()
