The \bTH command has a optional argument and when you print [<number>]
context take this as argument for \bTH. There are different ways to fix this,
one is to pass a empty argument to \bTH, e.g. "context.bTH{}" or you add \relax
after the command, e.g. "context.bTH() context.relax()".
BTW: You don’t need string.format because “context("[%d]",i)" is valid input.
