Summoned Fireballs Despawning after 1 second

When i try to summon a Fireball with no movement from commands the fireball despawns after 1 second i need this fireball for a custom map i'm making. Heres the command I used: /execute @e[type=blaze] ~ ~ ~ /summon fireball ~ ~1 ~

{CustomName:"Punch Me!",CustomNameVisible:1,ExplosionPower:2,direction:[0:0.0d,1:0.0d,2:0.0d]}
