var picker = Ti.UI.createPicker();
                picker.showDatePickerDialog({
                    callback: function(e) {
                        if (e.cancel) {
                            Ti.API.info('user canceled dialog');
                        } else {
                            Ti.API.info('user selected date: ' + e.value);
                        }
