我定义了动态呈现的文本字段的更改函数。但是得到了错误。"[Vue warn]: Property or method 'handleChange' is not defined on the instance but referenced during render...
这是Vuetify的bug还是我错了？

<v-col cols="12" sm="6" v-for="item in items">
   <v-text-field
      :label="item"
      @change="handleChange(item)"
   ></v-text-field>
</v-col>

method: {
  handleChange(item) {
    console.log(`${item} was changed`)
  }
}
