var dataSource = years.map(createItem);

richEdit.updateRibbon(function(ribbon) {
    ribbon.getTab(0).insertItem(new DevExpress.RichEdit.RibbonSelectBoxItem(
        'CustomDateSelectId', dataSource, {
        displayExpr: "text",
        valueExpr: "value",
        acceptCustomValue: true,
        onCustomItemCreating: function (e) {
            if (!e.customItem) {
                var item = createItem(parseInt(e.text));
                e.customItem = item;
                dataSource.push(item);
            }
