Angular kendo-sortable work with ng-repeat
Bound array on a kendo-sortable should update with no extra code
Needs like an k-model property or something similar to dragula so this is all handled internally in kendo
Makes no sense to claim angular support on the widget, but then have us manually move array elements around while not at all supporting sortable on an ng-repeat which every angular dev on the planet would be using for an array.
Right now the widget is just basically the bare minimum, but https://github.com/bevacqua/angular-dragula is the better option, just sucks to have to go outside of the ecosystem to get it to function like it should OOTB.
