Hunter Trap Launcher Glow/Sparkle Problem

[Pyth]

Hi I see in the WoW UI that the traps Glow when the Trap Launcher button is pushed. I cannot get the Glow/Sparkle to work using Macaroon. It works for my Focus Fire in Macaroon when the ability procs so I assume it should work for the Trap Launcher too. Any advice would be appreciated.
