You need “function() … end” around the inner content, it’s explained in the cld 
manual.

\setuppagenumbering[location=footer]

\setuplabeltext[en][willi=Willi Egger]
\startluacode
function documentdata.myheadertext(s)
    context.setupheadertexts{ function()
        context.labeltext("willi")
--      context.space()
        context(": ")
        context(s)
    end }
end   
\stopluacode

\ctxlua{documentdata.myheadertext("Headertext")}

\starttext
\input knuth
\stoptext
