Since the resize event clearly doesn't work (currently, at least), you can try one of these alternative options:

If you want really fine-grained control you can check in every mousemove event how much / if the div has been resized. If you don't need that, you can simply not use mousemove at all and just measure the div in mousedown and mouseup and figure out if it was resized in the latter.
2. Poll every 200ms or so (depending on your needs) and compare the current size with the last known size. See setTimeout().
