There is an embind example about passing a function pointer from C++ to JS
side, and calling it from JS. See here
https://github.com/kripken/emscripten/blob/master/tests/embind/embind.test.js#L1001
for the test.
What I'd do is create a small wrapper JS function that you add as the
callback to addEventListener, and that JS function then performs the
JS->C++ call of the function pointer.
