ListView ActiveX control AfterLabelEdit event does not fire when bound to a method of Container class

= BINDEVENT(THIS.lst, "AfterLabelEdit", THIS, "onlist_afterlabeledit")
* returns 1; tried with all possible flags
* the delegate has identical parameters with the source event

No troubles with binding ListView events ColumnClick, DblClick, ItemClick, MouseDown and MouseUp.

MSComctlLib.ListViewCtl.2 (version 6.0)
VFP8

What could be possibly wrong?
