Steps to reproduce

When the ref object r changes, the component regenerates the virtual dom for update. Why is c of type number updated, but objects rmb and data are not updated, but data.name.city is updated. 当ref对象r改变时，组件重新生成虚拟dom进行更新，为什么number类型的c更新了，而对象rmb和data没有更新，但是data.name.city却更新了呢.

And if you put the c and data objects of type number into one element, the data will be updated again! 如果把 number类型的c和data对象放到一个元素中，那么data又会更新了
