UI-State Calling other module controller - angularjs

Question

I am using webpack for bundling, and i have 4 module in angularJS(lets assume Management,Student,Teacher and Admin) so i have few js files names common in both management and admin. i am using webpack to create a single "bundle.min.js" file.
Now suddenly i add a feature to admin and i reload the page and find the ui-state router calling management controller insted of calleing admin controller.
my admin config file:
...
.state('admin',{
url:'',
views:{
'main':{
templateUrl:'adminPage.html',
controller:'AdminPageCtrl',
controllerAs:'$admin'},
}
})
...
config of management module
...
.state('management',{
url:'',
views:{
'main':{
templateUrl:'manPage.html',
controller:'AdminPageCtrl',
controllerAs:'$manage'},
}
})
...
admin index.js where i load all config and controllers:
var angular = require('angular'),
config = require('./config'),
adminPageCtrl= require('./controller/AdminPageCtrl');
module.exports = angular
.module('myApp.admin',[])
.controller('AdminPageCtrl', adminPageCtrl)
management index.js i load all config and controllers:
var angular = require('angular'),
config = require('./config'),
adminPageCtrl= require('./controller/AdminPageCtrl');
module.exports = angular
.module('myApp.management',[])
.controller('AdminPageCtrl', adminPageCtrl)
app.js where i load all modules
var angular = require('angular'),
adminModule = require('./admin/index'),
managementModule = require('./management/index'),
angular.module('myApp',['myApp.admin','myApp.management'])
The above is calling AdminPageCtrl of management module, instead of AdminPageCtrl of admin module.
