                                    }
                                },
                                {
                                    text: "Cancel",
                                    classes: "dark-blue-btn",
                                    click: function () {
                                        self.options.myDialog.close();
                                    }
                                }
                            ]
                        }
                    );

Put this code in action function

new SentFormModel(requestData).save(function (data) {
                        var getData = function () {
                            setTimeout(function () {
                                new SentFormModel().getSendStatus({id: data.id},
                                    function (data) {
                                        self.options.myDialog.open();
                                        self.options.count(data.count);
                                        
                                        console.log(data);
                                        if (!data.isComplete) {
                                            getData();
                                        }
                                    }, function (data) {
                                        console.log(data);
                                    });

                            }, 2000);
                        };
                        getData();
                    }, function (res) {
                        var errObj = eval("(" + res.responseText + ")");
                        new ErrorDialog('', errObj);
                        self.options.flag(true);
                    });
