onAfterHide doesn't work

jQuery("#list_table").on("click",".datetime-picker-click", function(ev){
        var el = jQuery(ev.target).parent().find('.datetime-picker');
        el.periodpicker({
            norange: true,
            // buttonClassSuffix: 'hidden'
            likeXDSoftDateTimePicker:true,
            timepicker: true,
            formatDate: convertMyDateFormatStringToMomentsString(dateformat),
            formatDateTime: convertMyDateFormatStringToMomentsString(datetimeformat),
            lang: _twoletterlangid,
            timepickerOptions: {
                ampm: (datetimeformat.indexOf('%p')>=0),
                twelveHoursFormat: (datetimeformat.indexOf('%p')>=0)
            },
            todayButton: true,
            onOkButtonClick: function () {
//some code
            },
            onAfterHide: function () {
                var val = this.startinput.val();
                if (!val || !moment(val, this.options.format).isValid()) {
                    this.addRange([new Date()]);
                }
            }
        });
        el.periodpicker('show');
        ev.preventDefault();
    });

The above code causes this error:
