I can't ride a mob with @trigger ~onInteract

Hey! today i was trying to make a driveable kart model with Model Engine & Mythicmobs, but i tried putting the mountmodel to work, but i tried the whole day and i got nothing, here's what the skills code looks like:

` Skills:

• model{mid=RaceKart} @self ~onSpawn
• mountmodel{mid=RaceKart;drive=true;mode=walking} @target ~onInteract
• message{m=Levei dano} @trigger ~onDamaged
• message{m=Fui interagido} @trigger ~onInteract `

Can someone help me?
