Is it possible to pass a C++ lambda as argument to a js function ?

Is the code below or equivalent possible ?
What is the best way to achieve this functionality ?

```cpp
class_>("_callback")
.constructor<>()
.function("opcall", &std::function::operator())
;

emscripten::val window = emscripten::val::global("window");

std::function wrapped = []() {
std::cout << "Hello " << "\n";
};

emscripten::val intervalId = window.call("setInterval", wrapped, 1000);
```

The code below does not work on the js side. It is called periodically but produce an error on each call
