If you're trying to bind a select box and you have select2 implemented, you're gonna have a bad time. Do this and it should fix most things with select dropdowns.

Select2 + Bindjs helper

        // Helper for Select2, since bind.js uses input events and select2 uses onchange.
        var inputChangeEvent = new Event('input');
        $('select').on("select2:select", function(e){
            e.currentTarget.dispatchEvent(inputChangeEvent);
        });
