                richconfig.suggest = config.suggest;

            var richselect: any = webix.ui(richconfig);
            richselect.attachEvent("onChange", function () {
                master.config.isFilterApplied = true;
                master.filterByAll();
            });

            config.richselect = richselect._settings.id;
            master._destroy_with_me.push(richselect);
        }

        config.css = "webix_div_filter";
        return " ";
    }
}, webix.ui.datafilter['serverDateRangeFilter']);

Hello,

Normally, we recommend not to use private (starting from _ ) methods and properties for custom components or any other functionality.

As a side note, new widgets can be created with webix.protoUI, it provides more possibilities that just extending.
