How to properly execute a function inside ng-repeat

Question

SITUATION:

I am making an app in AngularJs that assign permissions. In order to do this i have three nested ng-repeat.

First loop:

Answer 1

The subcategory example did not work for my case and it took my code into an infinte loop for some reason. may be because i was using an accordion.

I achieved this function call inside ng-repeat by using ng-init

      {{s.name}}
      

          {{p.name}}
      
 

The code on the controller side should look like below

$scope.getPresenters = function(id) {
    return SessionPresenters.get({id: id});
};

While the API factory is as follows:

angular.module('tryme3App').factory('SessionPresenters', function ($resource, DateUtils) {

        return $resource('api/session.Presenters/:id', {}, {
            'query': { method: 'GET', isArray: true},
            'get': {
                method: 'GET', isArray: true
            },
            'update': { method:'PUT' }
        });
    });
