Hideout component: "variable 'count' is not declared"

Working on a mod and when using the hideout component I'm not able to set a "OnGoHome" function because it runs into the error "scripts/components/hideout.lua"]:187: variable 'count' is not declared".

    inst:AddComponent("hideout")
	inst.components.hideout:SetGoHomeFn(OnGoHome)

Which leads back to this following code on the component:

function Hideout:GoHome( child )
    if self.storedcreatures[child] ~= nil then
        print("Ack! We already have this child inside!?")
        return
    end

    self.storedcreatures[child] = child
    self.numstoredcreatures = GetTableSize(self.storedcreatures)

    child:RemoveFromScene()
    child.Transform:SetPosition(0,0,0)
    if child.components.brain then
        BrainManager:Hibernate(child)
    end
    if child.SoundEmitter then
        child.SoundEmitter:KillAllSounds()
    end

    if self.ongohome then
        self.ongohome(self.inst, count)
    end

    if self.numstoredcreatures == 1 and self.onoccupied then
        self:onoccupied(self.inst)
    end
end

I believe "count" is not intended to be here and so causing the error. It would be great to be able to get this working, thank you in advance!
