Unable to listen to any of the events

[devWaleed]

My intro of app is working correctly but I am unable to listen to events.

In mounted of main App.js I have this code:

mounted: {

	this.$intro().onbeforechange(function (targetElement) {
	    console.log("before new step"); // no output
	    console.log(targetElement); // no output
	});

	this.$intro().onchange(function (targetElement) {
	    console.log("new step"); // no output
	});

	console.log('Post intro start', this.$intro()); // this prints some instance variables
}

introJS is chaining events and start() needs to be called here apparently. So correct way to do this is::

this.$intro()
.onbeforechange(function (targetElement) {
    console.log("before new step"); // no output
    console.log(targetElement); // gets element
})
.start();
