[NTG-context] How to show bibliography only for the chapter?

I am trying to place a bibliography at the end of the chapter, not the end of the whole document. I tried various code such as `criteria=bychapter` etc., but it will only show the entire bibliography for the whole document. How can I limit the list to the material falling within that chapter?     \starttext         \startchapter[title={Robots}]             \input knuth            \cite[source1]             \placelistofpublications[criteria=bychapter]             \placelistofpublications[way=bychapter]            \placelistofpublications[criteria=chapter]         \stopchapter     \stoptext --Joel
