NSSegmentedControl subclass and bindings

Subject: NSSegmentedControl subclass and bindings

I have a custom NSSegmentedControl that has non-standard width, thus, I'm subclassing mouseDown and mouseUp to select the proper segment. This works fine, but now I need to use bindings with the selectedIndex property. I can't get it to work at all, though... any pointers?

Here's my mouseUp method:
	unsigned newSelectedSegment; // assume this is calculated and valid
	[self willChangeValueForKey:@"selectedSegment"];
	[self setSelectedSegment: newSelectedSegment];
	[self didChangeValueForKey:@"selectedSegment"];

I've tried using willChangeValueForKey with selectedIndex but that did nothing to resolve the problem. Any tips on how to get my subclassing behaving with bindings?
