[NTG-context] indenting

I have the following enumeration: \defineenumeration [definition] [text=Definició,headstyle=bold,style=italic, between=\blank,titledistance=.5em, textdistance=1em,stopper=.,location=hanging,titleleft=(,titleright=)] and when I use it (\startdefinition ... \stopdefinition) it appears not indenting. I want to indenting it, but \indenting before \startdefinition does not work. How can do that? Thanks in advance, Xan.
