Listen to changes from nested model attributes

问题 I have a model attribute which is an object: name : "testing", orderCondition: { minOrderAmount: 20, deliveryCostRequire: "MIN_ORDER_AMOUNT", deliveryCostAmount: 5.55 } When I use listenTo like this, the render function is not called this.listenTo(this.model, "change:orderCondition", this.render); // NO FIRING But when I use listenTo on other attributes, it works. this.listenTo(this.model, "change:name", this.render); // FIRING Why listenTo doesn't see changes in nested objects but see them
