Scala can't figure out what type of parameter you mean, so you need to annotate
it -- "expand" -> (fooXhtml: NodeSeq) => {... }
Or use a separately named function with a type signature, e.g.
def doTheStuff(ns: NodeSeq): NodeSeq) = { Log.error(ns.toStrnig); <span /> }
bind(..., "expand" -> doTheStuff _)
