The layer is now only defined and has some content, but is not related to any
page element. So you has to define it as the background of some pageelement:
\setupbackgrounds[page][background=mylayer]
or you have to "flush" it (but I don't know what this is supposed to do, maybe
it's just another way of calling the OTR -- see below)
\flushlayer[mylayer]

OTR = Output Routine
Without invoking the OTR nothing is generated.
(but you can leave out \starttext \stoptext -- why?)

Both of these produce an empty page (without pagenumber) and the layer at the
intended position.

These two variants produce pages with the standard layout (in this easy setup
this consists only of the page number at the top).
The last alternative I know of: instead of defining the layer as background
for the page, you can just call
\flushlayer[mylayer]
But this positions the layer relative to the textarea (and not the pagearea)
and produces a standard layout with pagenumber, too, if you don't use
standardmakeup.
This has helped, to make some concepts regarding layers clear to me;-)
