我有一个叫做updateData的函数，每当有人点击一个单元格，我就想更新一个叫做state的数组中的那个单元格，它有3个对象，我想更新第一个对象的键。我尝试了很多方法，但似乎都不起作用，任何帮助都将不胜感激。

import Service from '@ember/service';
import { tracked } from '@glimmer/tracking';
import { action } from "@ember/object";

export default class TictactoeDataService extends Service {

    @tracked state = [{ "one": "1", "two": "", "three": "" }, { "one": "2", "two": "", "three": "" }, { "one": "3", "two": "", "three": "" }]
    get all() {
        return this.state
    }
    @action
    updateData(val) {
        this.state[0].two=val; // not updating 
        this.state=this.state // not working
    }
}
