Removeeventlistener Doesn't Work

I have this very strange case that prevents me from removing eventListener. This is a very simple function that binds to keyboard events and unbinds (in theory) when is not needed.

Solution 1:

You need to give the same function reference for removing from the event handler. Every time when you call the keyboardEvents, you create a new function with name keyboardFunction, so there are different from a call to call. So why you can't remove it.

Try this code Codepen.
