event name scroll.bs.scroll-spy.data-api is bad in two points.
First: namespace bs.scroll-spy is different to bs.scrollspy. Firstone is only used for this event, so I bet it is wrong.
Second: the event scroll has nothing to do with the data-api, so I remove it.
The better event name is: scroll.bs.scrollspy
And the registration of the load event handler should have a namespace. So I change it to load.bs.scrollspy.data-api.
