Version

1.4.0

Environment

win10/chrome latest/vue 1.4.0

Reproduction link

Steps to reproduce

升级到1.4.0后， a-radio-group组件如果绑定了字段，那么其事件就会执行两次（使用v-model或者form表单绑定）

<a-radio-group @change="onChange" v-model="tttt" defaultValue="a">
    <a-radio-button value="a">Hangzhou</a-radio-button>
    <a-radio-button value="b" disabled>Shanghai</a-radio-button>
    <a-radio-button value="c">Beijing</a-radio-button>
    <a-radio-button value="d">Chengdu</a-radio-button>
</a-radio-group>

onChange(e) {
    console.log(`checked = ${e.target.value}`);
},

What is expected?

点击后，change只执行一次

What is actually happening?

执行了两次
