使用jade时组件内的角度数​​据绑定不起作用

Question

我正在使用角度1.6.4和节点6.1，我正在尝试将我在player-main组件中指定的简单数组加载到模板，但它没有正确加载。

angular.
module('player').
component('playerMain', {
templateUrl: '/player.php',
controller: function PlayListController() {
    this.songs = [
        {
            id: 'one',
            title: 'Rain',
            artist: 'Drake',
            url: 'http://www.schillmania.com/projects/soundmanager2/demo/_mp3/rain.mp3'
        },
        {
            id: 'two',
            title: 'Walking',
            artist: 'Nicki Minaj',
            url: 'http://www.schillmania.com/projects/soundmanager2/demo/_mp3/walking.mp3'
        },
        {
            id: 'three',
            title: 'Barrlping with Carl (featureblend.com)',
            artist: 'Akon',
            url: 'http://www.freshly-ground.com/misc/music/carl-3-barlp.mp3'
        },
        {
            id: 'four',
            title: 'Angry cow sound?',
            artist: 'A Cow',
            url: 'http://www.freshly-ground.com/data/audio/binaural/Mak.mp3'
        },
        {
            id: 'five',
            title: 'Things that open, close and roll',
            artist: 'Someone',
            url: 'http://www.freshly-ground.com/data/audio/binaural/Things%20that%20open,%20close%20and%20roll.mp3'
        }
    ];

}
});

当模板网址被调用时，＆＃39; player.php＆＃39;快递路由器将其重定向到以下玉模板。

 .container
.row
    .col-md-12
        h5 Songs
        ul
            li(ng-repeat='song in $ctrl.songs')
                button(music-player='play', add-song='song') {( song.title )}
                button(music-player='', add-song='song') +
        button(play-all='songs') Play all
        button(play-all='songs', data-play='false') Add all
hr

但即使ng-repeat确实迭代了数组5次，

{(song.title)}

没有得到评估，它只是将其打印为字符串。
