This is due to suppressed expansion when saving the titles. 

\stellijstin[hoofdstuk][expansie=ja] 

is ene oplossing, maar beter kun je het synoniemen mechanisme gebruiken,
zie \afkorting (\abbreviation). Bijkoment voordeel is dat je dan de
gebruikte auteurs kan oproepen.

\definieersynoniem[Auteur][Auteurs][\Boek]

\Auteur {FRANS} {Frans Goddijn} { \ConTeXt\ voor experts}

\stelhoofdtekstenin [\FRANS] [\Boek{FRANS}]

Nu kun je ook opvragen

\plaatslijstmetAuteurs

Just turn expansion on. 

\expanded{\hoofdstuk{...}} would have worked also

Just use \def. Suggestion: use capitals to prevent name clashes with
internal commands.
