How to restore default zoom behaviour after specifying ActionPostCallback

After altering the zoom behaviour of a figure axes inside a GUI with: set(zoom(axh),'ActionPostCallback',@datetickzoom),

later on, I make a different plot in the same GUI figure axes and don't want datetickzoom to be triggered anymore when I use the zoom. How can I disable that customised ActionPostCallback setting and basically return zoom to default behaviour?
