antd-mobile 的 datepicker 的onchange事件不响应

import React, { Component } from 'react';
import { DatePicker, List } from 'antd-mobile';
import './Home.css';
class Home extends Component {
    constructor (){
        super();
        this.state = {
            date : new Date(Date.now())
        };
    }
    detechange(){
        console.log("123123");
    }
    render() {
        console.log(window.devicePixelRatio);
        console.log(document.documentElement);
        console.log(window.innerWidth/window.innerHeight);
        return(
            <div className = "home">
                <DatePicker
                  mode="date"
                  title="Select Date"
                  extra="Optional"
                  onChange={ () => this.detechange()}
                >
                  <List.Item arrow="horizontal">Date</List.Item>
                </DatePicker>
            </div>

        )
    }
}
export default Home;
