Ion-slides help (swiper, ionic 1.3.1)

I have a gallery with 4 pictures. When i delete one slide from this gallery, no run slidechange event.
I would like to if i remove one slide, run this… i see $scope.slider.slideNext(); go next slide, this animate, but when i remove previous slide, slider items move left one item.
If first remove item, this show next slide, and no animate

So how to remove a slide with slidechange

is this bug on picture?
