Calling ED_region_tag_redraw is no good, checked the patch.
The reason RNA_property_update doesn't work is the button doesnt
reference any RNA where though its rna from &but->rnapoin,
but->rnaprop - they are NULL and crash for me.
Instead it relies on but->funcN callback, see use of 'RNAUpdateCb'
So probably best to do what 'paste' does and fake user button editing:
button_activate_state(C, but, BUTTON_STATE_NUM_EDITING);
... edit colorband ...
button_activate_state(C, but, BUTTON_STATE_EXIT);
This works for colorband delete.
