Having written this, I’ve looked a bit further and discovered the 
‚IKendoEditor‘ interface.
As used like here:
https://github.com/sebfz1/wicket-jquery-ui/blob/wicket9.x/wicket-kendo-ui/src/main/java/com/googlecode/wicket/kendo/ui/datatable/editor/TextAreaEditor.java

Seems like this should be used to modify model when in an ‚edit‘ mode.
