javascript - AngularJS resetting array of arrays -

-

i asked question similar , tried solution worked no luck. pretty simple problem. have following : 

<script type="text/javascript"> 'use strict'; var app = angular.module('app', ['appcontrollers']); "use strict"; var appcontrollers = angular.module('app', []); appcontrollers.controller('personcontroller', ['$scope', '$http', function ($scope, $http) {  $scope.responses = [[], [], []];  $scope.addcoach = function() { $scope.responses[0].push($scope.coach.name); }; $scope.addathlete = function() { $scope.responses[1].push($scope.athlete.name); }; $scope.addsupportstaff = function() { $scope.responses[2].push($scope.employee.name); };

so i'm trying add list of coaches, athletes , supporting staff respective arrays within array when check console log of $scope.responses shows added one.

edit:

so i've changed code following:

<script type="text/javascript"> 'use strict'; var app = angular.module('app', ['appcontrollers']); "use strict"; var appcontrollers = angular.module('app', []); appcontrollers.controller('personcontroller', ['$scope', '$http', function ($scope, $http) {  $scope.responses = { coaches: [], athletes: [], employees: []    };  $scope.addcoach = function() { $scope.responses.coaches.push($scope.coach.name);  console.log($scope.responses); $scope.coach = {}; // clean form fields };  $scope.addathlete = function() { $scope.responses.athletes.push($scope.athlete.name);  console.log($scope.responses); $scope.athlete = {}; // clean form fields };  $scope.addsupportstaff = function() { $scope.responses.employees.push($scope.employee.name);  console.log($scope.responses); $scope.employee = {}; // clean form fields };

}]);

html

<h1>coaches attending</h1> <div data-ng-app="app" data-ng-controller="personcontroller"> <div> <div> <input type="text" class="span3" placeholder="full name" ng-model="coach.name"> <button type="button" ng-click="addcoach()">&nbsp;&nbsp;add&nbsp;&nbsp;</button>   </div> <div >     <ul><li ng-repeat="coach in responses.coaches">{{coach}}</li></ul> </div> </div>  <br>   <h1>athletes attending</h1> <div data-ng-app="app" data-ng-controller="personcontroller"> <div> <div> <input type="text" class="span3" placeholder="full name" ng-model="athlete.name"> <button type="button" ng-click="addathlete()">&nbsp;&nbsp;add&nbsp;&nbsp;</button>   </div> <div >     <ul><li ng-repeat="athlete in responses.athletes">{{athlete}}</li></ul> </div> </div>  <br>   <h1>support staff attending</h1> <div data-ng-app="app" data-ng-controller="personcontroller"> <div> <div> <input type="text" class="span3" placeholder="full name" ng-model="employee.name"> <button type="button" ng-click="addsupportstaff()">&nbsp;&nbsp;add&nbsp;&nbsp;</button>   </div> <div >     <ul><li ng-repeat="employee in responses.employees">{{employee}}</li></ul> </div> </div>

but problem when add in coach column after adding in athlete or support staff, removes previous entries.

fixed it. defining controller , app multiple time giving multiple instances.
