This can be the problem if you have set your drop down style as "DropDownList".
Instead change it to "DropDown".
I hope this will solve it.

Lalit,
I tried setting it to DropDown instead of DropDownList. The event
still doesn't fire off. I did, however, came up with a workaround.
I'm simply calling my logic just after filter applied. I'm still
curious how this can work. Thank you for your suggestion. Sorry for
the late post.
