Those callbacks are not exposed to the Javascript side, they are only available from C++ code. The reason is the support for multipolygons in osmjs by reading the file twice. Its unclear when those callbacks should "fire". You can work around this by remembering in global variables whether the other callbacks were called and do some things when they are called for the first time. I realize this is not optimal (and probably not documented). I am unhappy with the way Javascript callbacks are done anyway, but don't know yet how best to fix that, so it will probabyl not change anytime soon. > are not performed.
