And since script is loaded in qanda : can not be replaced

Current solution : adding this at end of layout_global

            <script>
                var doMultipleChoiceWithComments = function(qID,when) {  console.warn([qID,when]); };
            </script>

But since there are an unregisterScriptFile function, i think it muts unregister the script file
There are a lack of $position in unregisterScriptFile
