Bandit and katarina.

so bandit says spell or attack. and i saw a video stating u could use spells like maoki's seedling and galios Q to hit the bandit proc in lane. so i thought why not try it on katarina. however maybe i am blind but everytime i throw my dagger it doesnt seem to proc or atleast both the bandit CD icon doesnt show and the gold gain doesnt show on hit. is this intentional and if so why, or is this me just being blind and failing to notice the 10g gain.
