Ng-click not working if you slide the wrong way with SlideBox

Has anyone run into issues with processing ng-click with the slidebox, but only if you slide to the right?

My slidebox has does-continue enabled. I have a link on the second (index 1) slide. However, the ng-click attribute fires only if I access that slide by sliding to the left. Accessing the same slide from the other direction does not fire ng-click. Bizarre!

Further, from the wrong direction, if I cycle through the slidebox twice, it then processes ng-click.
