not showing custom tooltip

Hi i’ve put this in my code, the timeline is named “timeline” ,
but in the console i get nothing and the tooltip showed it’s always the default.

scheduler.templates.timeline_tooltip = function(start, end, event) {
console.log (“test test”);
return event.text;

You could save default template and use it if mode isn’t timeline.
