Cascader :defaultValue默认值不能动态绑定

[ciel-he]

• I have searched the issues of this repository and believe that this is not a duplicate.

Version

ant-design-vue 1.3.10

Environment

最新，Chrome，vue2.5

Reproduction link

Steps to reproduce

1、改变switch，就改变对应的options和默认值
2、改变默认值并没有显示，始终只有第一次绑定的值显示，之后改变输入框都是显示为空

What is expected?

默认值可以动态绑定

What is actually happening?

改变之后，输入框显示为空

---

现在使用v-model代替defaultvalue显示，可以得到预期效果
