Horizontal and vertical ion-slides pagination

has anyone got vertical ion-slides embedded in horizontal ion-slides, and had the pagination for each visible ? Mine aren’t showing on iOS or Android or web (ionic 1.2.1).

In the options for the horizontal slider, i specified
pagination: ‘.swiper-pagination-h’,

In the options for the vertical slider, i specified
pagination: ‘.swiper-pagination-v’,

I did that per the nested slider demo:

Am i missing something else to have the embedded paginators show?
