The event is fired for column “a” but not for column “b”
The onEditorChange event is similar to the html onchange for the editor’s input. Therefore, it will occur for the ‘text’, and ‘select’, but unfortunately, it will not work for such editors as ‘richselect’ and ‘popup’.
By the way, we’ve found this information is missing in our Docs, thanks for drawing attention to it.
