onWorksheetChange not working with Data Validation

Hello!
I’m having a problem with the onWorksheetChange event, which is supposed to fire when a list cell is changed (Data Validation > List).
If the list source is static comma-separated values, the event fires, but if a range from the same sheet is specified, the onWorksheetChange event doesn’t fire.
My code:

(function(window, undefined) {
    window.Asc.plugin.init = function() {
        this.callCommand(function() {
			console.log("Run: callCommand");

			Api.attachEvent("onWorksheetChange", function(oRange) {
				console.log("Fired: onWorksheetChange");
			});
		}, false);
    };
})(window, undefined);

Hello @tu283

We are aware of this issue. The work is in progress.
