Run a function after the options are rendered.

[shobhit10058]

I am encountering a use case, where I need to run mathjax typeset after the options are rendered, currently, I am doing it by onMenuOpen event and then using settimeout for some time so that the options are rendered, but this will cause issues on deciding the correct limiting time. Is there any workaround for this?
