Custom Directive - Using Template Via Function

In Custom Directive - Using a Template you saw how to use the template property to indicate a HTML template. The template property can also be used to specify a function that returns  the templated content. The function has two arguments:
  • the element to which the directive has been applied
  • several  attributes
The function returns the fragment of HTML:

<!DOCTYPE html>
<html>
<head lang="en">
    <meta charset="UTF-8">
    <title></title>
    <script src="../angular/angular.min.js"></script>
    <style type="text/css">
    </style>
    <script type="text/template" id="orderListTemplate">
        <ol type='i'>
            <li ng-repeat='item in players'>{{item.prizemoney | currency}}</li>
        </ol>
    </script>
    <script>
        angular.module("appModule", [])
                .controller("appCtrl", function ($scope) {
                    $scope.players = [
                        { name: 'Nadal, Rafael (ESP)', rank: 1, age: '28', prizemoney: 66149345 },
                        { name: 'Djokovic, Novak (SRB)', rank: 2, age: '27', prizemoney: 70704129 },
                        { name: 'Federer, Roger (SUI)', rank: 3, age: '33', prizemoney: 84827704 },
                        { name: 'Wawrinka, Stan (SUI)', rank: 4, age: '29', prizemoney: 13155060 },
                        { name: 'Ferrer, David (ESP)', rank: 5, age: '32', prizemoney: 24034072 },
                        { name: 'Tsonga, Jo-Wilfried (FRA)', rank: 11, age: '29', prizemoney: 1708240 },

                    ];
                    $scope.updatePrizeMoney = function () {
                        angular.forEach($scope.players, function (player) {
                            player.prizemoney = player.prizemoney +
                                     Math.floor((Math.random() * (900000 - 10000) + 10000));
                        });
                    }
                })
                .directive("orderedList", function () {
                    return {
                        link: function (scope, element, attrs) {
                            var data = scope[attrs["orderedList"]];
