搜索骨干集合的问题

Question

我有这个bb应用程序，我正在尝试搜索并返回搜索结果，然后在清除时，所有结果再次。在添加搜索功能之前，我能够显示所有内容，但现在没有显示任何内容。我认为该系列在尝试填充时不可用，但似乎无法让它等待。我试过移动取消无济于事。任何帮助都会非常感激。为了方便起见，我把所有东西都放在了这里可以找到的小提琴......

//Campaign Model w defaults
app.model.Campaign = Backbone.Model.extend({
    default: {
        title: '',
        img: '',
        id: '',
        slug: '',
        image_types: 'small',
        tagline: ''
    }
});


//Campaign Collection from model

        return _(this.filter(function(data){
            console.log('currentStats', status);

//Item view for single campaign

app.router.campaigns = new app.router.Campaign();
Backbone.history.start();
