If you want to keep on adding decorators, then try something like this
inside the onscroll listener:
var band = tl.getBand(0)
var decorator = new Timeline.SpanHighlightDecorator({ /* parameters
*/ });
band._decorators.push(decorator);
decorator.initialize(band, tl);
decorator.paint();
But I'd recommend using the same decorator and changing its dates. So,
at the beginning, create a decorator and keep a reference to it. Then
whenever you need to shift its dates, do something like this
decorator._startDate = // some date here
decorator._endDate = // some date here
decorator.paint();
