onStructureUpdate in Webix Pivot

Webix JS
#1

Hi, I see that datagrid has onStructureUpdate event available, but pivot doesn’t. Is there any workaround to subscribe to onStructureUpdate in Webix Pivot?

Datatable available as $$("pivot").$$("data"), i.e.

$$("pivot").$$("data").attachEvent("onStructureUpdate", function(){})
