How are you starting the asynchrounous call ?
So you would have flow like this
Some Bussiness Logic
Invoke AsynCall ---------------------> Will continue
AsyncCall -------> Ends later .(This can't have control of TX as that is ended earlier)
Async Call should end before the END TX , then it would be useful.
So asnchronous does not add value here .
