自定义组件实现v-model,如何绑定组件内的多个值?

自定义组件MyComponent实现v-model

<template>

<div>
    <my-component v-model="person"></my-component>
</div>

</template>

MyComponent组件内部有四个input,比如

<input  type="text" :value="name">
<input  type="text" :value="sex">
<input  type="text" :value="age">
<input  type="text" :value="job">

这种情况下如何实现动态双向数据绑定,让person的值是组件内四个input的值组成的字符串?输入框里的值更改后,person的值动态改变,从而实现v-model?
