No Context when using hyper dom expressions

I've this strange behaviour that

useCounter(CounterContext)

useCounter(CounterContext)

useCounter(CounterContext)

useCounter(CounterContext) returns

undefined

undefined

when porting the context example to use hyper dom expressions.

Any ideas what I am doing wrong?
