骨干无限集合获取所需响应的调用？

我打电话给一个rest服务器的触发站点刷新的API。然后我需要调用另一个API（另一个集合获取）来检查网站刷新是否完成。我需要调用第二个API，直到我得到siteRefresh =“completed”。我如何以骨干的方式做到这一点。骨干无限集合获取所需响应的调用？

我的看法代码是这样的

define(['collections/firstCollection', 
'collections/secondCollection', 
], function(firstCollection, secondCollection) { 
var memAccId; 
var refreshView = Backbone.View.extend({ 
    tagName : 'div', 
    className : 'refresh-wrap', 
    initialize : function() {   
     var self = this;  
      self.collection = new firstCollection(); 
      self.collection.fetch({ 
       timeout : 50000, 
       type : "POST", 
       data : data,      
       success : function(response) { 
        var result = response.toJSON(); 
        if (typeof result[0].Id !== "undefined") { 
       memAccId=result[0].Id; 
        $(self.$el).trigger('onAccountId'); 
         } 

        }, 
        error : function(request, status, error) { 
         console.log("ERROR - first Collection on fetch error."); 

        } 

       });   
     }, 
     events : { 
      'onAccountId' : 'getRefreshInfo' 
     }, 
     getRefreshInfo : function() { 
     var self = this; 
      self.collection = new secondCollection(); 
      self.collection.fetch({ 
       timeout : 30000, 
       type : 'POST', 
       data : {"Id":memAccId}, 
       success : function(response) { 
      if(response.refreshStatus !=="REFRESH_COMPLETED"){ 
        // self.collection.fetch(); 
        //how to call this collection fetch until i get refreshStatus = 
"REFRESH_COMPLETED" 
      } 
      }, 
        error:function(request, status, error){ 

      } 
      }); 
      } 
     } 
    }); 
    return refreshView; 
});
