vue v-model 与 vuex state数据绑定问题

最近开发的项目 需要用input 的v-model 直接绑定到vuex的store数据 因为v-model 能与data的数据绑定 尝试了半天 

代码如下

<template>
  <div>
    <el-row class="age">
        <el-col :span="3">
          <div class="el-input__inner agestart">
            <el-checkbox v-model="changeValue">年龄</el-checkbox>
          </div>
        </el-col>
        <el-col :span="4">
          <el-input type="number" v-model="content" placeholder="开始年龄"></el-input>
        </el-col>
        <el-col :span="2">
          <div class="el-input__inner ageto">
            to
          </div>
        </el-col>
        <el-col :span="4">
          <el-input type="number" v-model="contentend" placeholder="结束年龄"></el-input>
        </el-col>
      </el-row>
  </div>
</template>
<script>
import { mapState } from 'vuex'
export default {
  name:'Age',
  computed:{
    changeValue:{
      get(){
        return this.$store.state.changeValue
      },
      set(v){
        this.$store.dispatch("changeMy",v)
      }
    },
    content:{
      get(){
        return this.$store.state.startAge
      },
      set(v){
        this.$store.dispatch('changeMoney',v)
      }
    },
    contentend:{
      get(){
        return this.$store.state.endAge
      },
      set(v){
        this.$store.dispatch('changeEndAge',v)
      }
    }
  }
}
</script>
<style lang="stylus">

</style>
