I'm going to have the value be modelChange, and then…I'm going to dispatch an event. It's going to dispatch the string here.…
So we can listen for that modelChange event.…Scroll down and at the bottom of setCurrentIndex, below everything else inside…of there, we are going to dispatch that modelChange event. I'll do that using…the dispatchEvent method. So dispatchEvent.
