我重构了你的代码。我还提出了一些意见，以帮助您实现目标并更多地了解主干。

initialize: function() {
    var self = this;
    _.bindAll(this, 'render');
    this.collection = new FieldCollection();
    this.collection.parse();

    this.collection.fetch({
        success: function (collection, response) {
            console.log(response);
            self.render();
        }
    });
},

render:function(){
    var self = this;
    _.each(this.collection, function(model) {
        // here you should create subviews and delegate events within particular view
        // i.e:
        // self.buttonViews.push(new ButtonView({ model: model}));
        // but for now you can use data-id attribute to match the button you clicked
        $(self.el).append("<button class='myName' data-id=" + model.id + ">" + model.name + "</button><h1>" + model.img + "</h1><br/>");
    });     
},

namefunc:function(){
    //use data-id attribute we put in button tag earlier to catch the id
    //and use this.collection.get('id') function to get the model you want to get parameters of
}

绑定一个按钮
