Although what @machineghost said was true, that events are added and removed the same way, the missing part of the equation was this:
A new function reference is created after
.bind()
is called.
See Does bind() change the function reference? | How to set permanently?
So, to add or remove it, assign the reference to a variable:
var x = this.myListener.bind(this);
Toolbox.addListener(window, 'scroll', x);
Toolbox.removeListener(window, 'scroll', x);
This works as expected for me.
