Cast on Crit and ice spear interaction

Hi, i'm running a Coc build and for my single target i use

Barrage - GMP - CoC - Fireball - Artic Breath - ice spear

My question is: The crit thath i do when the ice spear(triggered by coc) reach it's end will trigger the coc process again?

Thanks.

No. Read the description of the skill gem - it says attacks

the only attack in your setup is barrage

I was shure of it at 90% but i have to ask aniways.

Thanks.
