angularjs - How can you iterate through controllers in an ng-repeat from the parent? -


i want write loop goes through of child controllers , runs function in them. @ moment code running function in 1 instance of child controller. how iterate through instances of controller, generated through ng-repeat?

basically, on click of button function in childcontroller should run 4 times, 1 each controller generated on each 'set' in 'wordlistsets'.

html: 

<button ng-click="setall(true)">select all</button><button ng-click="setall(false)">deselectall</button> <ul>    <li ng-repeat="set in wordlistsets" ng-controller="setcontroller">        <div class="parentselector">           <input type="checkbox" ng-click="selectallchildren(set.content)" ng-checked="parentchecked">        </div>         <div ng-repeat="wordlist in set.content"  ng-click="togglecheckbox(wordlist)">           <input type="checkbox"  ng-checked="checkedwordlists.indexof(wordlist)> -1">        </div>    </li> </ul>

angular controllers:

myapp.controller("parentcontroller", function ($scope) {    $scope.setall = function(value) {        var index;        (index in $scope.wordlistsets) {            $scope.setall.selectallchildren($scope.wordlistsets[index].content, value);        }    }; });  myapp.controller("childcontroller", function ($scope) { $scope.parentchecked = false; $scope.checkedwordlists = [];  $scope.selectallchildren = function(wordlists) {     if ($scope.parentchecked == false) {         $scope.parentchecked = true;     } else {         $scope.parentchecked = false;     }      var index;     (index in wordlists) {         $scope.setchild(wordlists[index], $scope.parentchecked);     } };  $scope.setall.selectallchildrenvalue = function(wordlists, value) {     if (value == false && $scope.parentchecked == true) {         $scope.parentchecked = false;     } else if (value == true && $scope.parentchecked == false) {         $scope.parentchecked = true;     }      var index;     (index in wordlists) {         $scope.setchild(wordlists[index], $scope.parentchecked);     } };  $scope.togglecheckbox = function(wordlist) {     var index = $scope.checkedwordlists.indexof(wordlist);      if (index > -1) {//is in array         $scope.checkedwordlists.splice(index, 1);//remove array     } else {         $scope.checkedwordlists.push(wordlist);//add array     } };  $scope.setchild = function(wordlist, parentchecked) {     var index = $scope.checkedwordlists.indexof(wordlist);      if (parentchecked && index <= -1) {//is not in array         $scope.checkedwordlists.push(wordlist);//add array     } else if (!parentchecked && index > -1) {//is in array         $scope.checkedwordlists.splice(index, 1);//remove array     } };  });

i know didn't many answers made me realize in fact, thinking backwards. set "checked" property in json data , set ng-checked. setall function, iterated through json foreach , set each .checked value = true/false. :)
