You need

  \setupbackend[export=yes]

in your document. When you put the setup above in a "epub"
mode you create a epub-document only when you enable the mode
which is recommended because it can have side effects for
the normal PDF.

To avoid these side effects make an extra ConTeXt run
by enabling the mode to get the epub file.
