I have kept my controller source in my app.js. But i planned to move the specific controller into the corresponding root folder. Lets say i have home controller code in app.js. Now i want to move it to homecontroller.js which placed in home folder. I tried that. but it doesn't work for me. However it works when i keep that in app.js. Can you help me to move it to desired root.
my app.js is
var app = angular.module('TrailApp', ['ui.router'])
app.config(function($stateProvider, $urlRouterProvider) {
    $urlRouterProvider.otherwise('/home/part1');
    $stateProvider
        .state('base', {
          abstract: true,
          url: '',
          templateUrl: 'app/app.html'
        })
        .state('home', {
          url: '/home',
          parent: 'base',
          templateUrl: 'app/home/home.html',
          controller: 'homectrl'
        })
           .state('home.part1', {
              url: '/part1',
              templateUrl: 'app/home/part1.html',
              //controller: 'homectrl'
            })
            .state('home.part2', {
              url: '/part2',
              templateUrl: 'app/home/part2.html',
              //controller: 'homectrl'
            })
        .state('about', {
          url: '/about',
          parent: 'base',
          templateUrl: 'app/about/about.html',
          //controller: 'aboutctrl'
        })
  });
 //This below code should be moved to homecontroller.js 
app.controller('homectrl', ['$scope', '$location', '$rootScope',
  function($scope, $location, $rootScope) {
      $scope.custom = false;
      $scope.actionBtn = function(event) {
            $scope.custom = true;   
      };
  }
]);
