angularjs - directive only works inside another directive -

i made directive filtering data. uses scope: true , no transclusion. somehow works inside ng-switch. maybe other directives havent tried.

my html looks this:

<my-filter source="{{foodarray}}" filter="reaction,category"> // source , filter properties on directive scope     <div>         <div class="span3">             <table class="table table-bordered">             <tr data-ng-repeat="item in filters.reaction"> // filters property of directive scope                 <td><input type="checkbox" data-ng-model="item.ischecked" data-ng-change="filterctrl.filterlist()"></td>                 <td>{{ item.value }}</td>             </tr>         </table>         </div>     </div>     <table>         <tbody>             <tr data-ng-repeat="food in filtereddata"> // filtereddata object on directive scope                 // interating through filtereddata             </tr>         </tbody>     </table> </my-filter> 

here directive , controller:

angular.module('mymodule', []) .directive('myfilter', function() {     return {         restrict: 'e',         scope: true,         controller: ["$scope", function ($scope) {             var filterctrl = this;             $scope.filters = {};             filterctrl.inputarray = [];              filterctrl.filterlist = function() {                 /* code tmp array created */                  $scope.filtereddata = tmp;             }            }],         controlleras: 'filterctrl',         link: function(scope, element, attrs, filterctrl) {             filterctrl.inputarray = angular.fromjson(attrs.source);             scope.filtereddata = filterctrl.inputarray;              // ...         }        } });  

filtereddata , filters property of directives scope. when remove ng switch around data empty. scope.source property can array or object. when remove ng switch , give object source throws syntax error: syntaxerror: unexpected end of input @ object.parse (native) @ object.fromjson

which doesnt throw when use array.

not sure make of this. if had problem before love hear you.
