My code is as below -

    <script type="text/javascript" src="angular.min.js"></script>
</head>

<body>
    <div data-ng-controller="simpleController">
        <input type="text" data-ng-model='name' />
        <ul>
            <li data-ng-repeat='customer in customers | filter:name | orderBy:"city"'>{{customer.name | uppercase}} - {{customer.city|lowercase}}</li>
        </ul>
    </div>
    <script type="text/javascript">
        function SimpleController($scope) {
            $scope.customers = [{
                name: 'John Doe',
                city: 'Pheonix'
            }, {
                name: 'John Smith',
                city: 'New York'
            }, {
                name: 'Jane Doe',
                city: 'San Fransisco'
            }];
        }
    </script>

You must inject your controller into application module.

Give your app a name:

<html ng-app='myApp'>

Inject controller:

var app = angular.module('myApp', []);
app.controller('SimpleController', function($scope) {
    $scope.customers = [
        { name:'John Doe',city : 'Pheonix'},
        { name : 'John Smith',city: 'New York'},
        { name : 'Jane Doe',city : 'San Fransisco'}
    ];
}

Controller simpleController should be registered under angular app.

see the working code below.

var app = angular.module('app', []);

app.controller('simpleController', function($scope) {
  $scope.customers = [{
    name: 'John Doe',
    city: 'Pheonix'
  }, {
    name: 'John Smith',
    city: 'New York'
  }, {
    name: 'Jane Doe',
    city: 'San Fransisco'
  }];
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<div ng-app='app'>
  <div data-ng-controller="simpleController">
    <input type="text" data-ng-model='name' />
    <ul>
      <li data-ng-repeat='customer in customers | filter:name | orderBy:"city"'>{{customer.name | uppercase}} - {{customer.city|lowercase}}</li>
    </ul>
  </div>

</div>

Your code is absolute correct for the angular version less than 1.3 except the function name spelling. It should be data-ng-controller="SimpleController" while calling as you have declared.

You can try after including following cdn

https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.2.1/angular.js

You are not defined angular.module in your script.

   <head>
        <title>Angular ng-controller</title>
        <script type="text/javascript" src="angular.min.js"></script>
    </head>

    <body ng-app='filterApp'>
        <div ng-controller="simpleController">
            <input type="text" data-ng-model='name' />
            <ul>
                <li ng-repeat='customer in customers | filter:name | orderBy:"city"'>{{customer.name | uppercase}} - {{customer.city|lowercase}}</li>
            </ul>
        </div>


         <script type="text/javascript">
         var app = angular.module('filterApp', []);
         app.controller('SimpleController', function($scope) {
                       $scope.customers = [{
                        name: 'John Doe',
                        city: 'Pheonix'
                    }, {
                        name: 'John Smith',
                        city: 'New York'
                    }, {
                        name: 'Jane Doe',
                        city: 'San Fransisco'
                    }];
                }
            </script>
        </body>
