Essentially, TEXpage is a fancy \frame (which, in turn, is a fancy \vbox). 
So, you cannot get the regular footnote mechanism inside TEXpage. If you 
do need footnotes, you can use localfootnotes:

\starttext
\startTEXpage[width=0.6\textwidth, offset=3mm]
   \startlocalfootnotes
       Knuth:\footnote{The creator of \TEX}
       \input knuth

       \placelocalfootnotes
   \stoplocalfootnotes
\stopTEXpage
\stoptext
