有沒有理由在Backbone.js中避免這種情況？

我越來越喜歡backbone.js。我希望對於給定模型有多個視圖：有沒有理由在Backbone.js中避免這種情況？

列表視圖，其中每個模型都有一個包含它自己的li元素的視圖。
一個詳細視圖，顯示模型的所有細節。

我的問題是，我正在尋求一個很好的方式，讓一個視圖與另一個溝通，選出了以下：

/** Allow a model to keep track of it's views. **/ 
Backbone.Model.prototype.addView = function (view) { 
    // Ensure our model has a view array. 
    if (typeof this.views === 'undefined') 
    { 
     this.views = []; 
    } 

    // Append our newest view to the array only if it is not already present. 
    if (_.indexOf(this.views, view) === -1) 
    { 
     this.views.push(view); 
    } 
} 

/** Allow a model to remove all of it's views. 
* 
* @param {Object} args Any arguments will be provided to the view's method. 
*/ 
Backbone.Model.prototype.unloadViews = function (args) { 
    var n = (typeof this.views === 'undefined') ? 0 : this.views.length; 
    for (var i = 0; i < n; i++) 
    { 
     var view = this.views[i]; 
     if (typeof view.unloadView === 'function') 
     { 
      view.unloadView(args); 
     } 
    } 
} 

/** Allow a model to re-render all of it's views. 
* 
* @param {Object} args Any argyments will be provided to the view's method. 
*/ 
Backbone.Model.prototype.renderViews = function (args) { 
    var n = (typeof this.views === 'undefined') ? 0 : this.views.length; 
    for (var i = 0; i < n; i++) 
    { 
     var view = this.views[i]; 
     if (typeof view.render === 'function') 
     { 
      view.render(args); 
     } 
    } 
}
