Class cWorld; Function ScheduleTask; Only one Function Callback

[VeryBlackMan]

Hallo,

I want a ticker that calls a function every 5 minutes.
This is my Code.

Code:

function Initialize(Plugin)
  Plugin:SetName("MyPlugin")
  Plugin:SetVersion(1)
  local World = cRoot:Get():GetDefaultWorld()
  World:ScheduleTask(10, TaskFunction)
  return true
end

function TaskFunction(World)
  LOG(World:GetName())
end

But the Function TaskFunction is called only once.
Why this?
