What is a way to catch a change of the value in the checkboxes in the ui.property. onAfterEditStop doesn’t work in this case as there is no actual editing.
Checkboxes in ui.datatable and ui.property support onCheck event: https://webix.com/snippet/22e3e4b4
Great, it turned out I was using old version of Webix, where it was not working yet. But all set now. Thank you.
