vertical-grid.html

<div class="provider-photos row">   <div class="{{$ctrl.colcssclass}}" ng-repeat="col in $ctrl.colgrid track $index">     <div class="photo-outer-tile" ng-repeat="cell in col track $index">       <div class="photo-tile">         <img ng-src="{{cell.tile_url}}">         <div class="photo-controls">           <a ng-click="$ctrl.deletephoto(cell.id)" href="javascript:void(0);">delete</a>           <a  href="javascript:void(0);">crop</a>         </div>       </div>     </div>   </div> </div>

to communicate between angularjs controllers use service (or factory, conceptually similar).
see example here.
can propagate events in real-time service controllers using $watch concept.

a simpler way use inject $rootscope in both controllers.
