How to implement multiple checkbox using react hook

I want to implement multiple checkbox on my html page using react-hook.

I tried implementing using this URL: https://medium.com/@Zh0uzi/my-concerns-with-react-hooks-6afda0acc672 . In provided link it is done using class component and working perfectly but whenever i am using react hook setCheckedItems to update checkbox checked status its not re-rendering view. Very first time view is rendering and console.log() is printing from Checkbox component. After clicking on checkbox function handleChange gets called and checkedItems updates the value but view is not rendering again (no console.log() printing). And {checkedItems.get("check-box-1")} is also not printing any value.

Below is my sample code.

CheckboxExample :

import React, { useState } from 'react';
import Checkbox from '../helper/Checkbox';

const CheckboxExample = () => {
    const [checkedItems, setCheckedItems] = useState(new Map());

    const handleChange = (event) => {
        setCheckedItems(checkedItems => checkedItems.set(event.target.name, event.target.checked));
        console.log("checkedItems: ", checkedItems);
    }

    const checkboxes = [
        {
            name: 'check-box-1',
            key: 'checkBox1',
            label: 'Check Box 1',
        },
        {
            name: 'check-box-2',
            key: 'checkBox2',
            label: 'Check Box 2',
        }
    ];


    return (
        <div>
            <lable>Checked item name : {checkedItems.get("check-box-1")} </lable> <br/>
            {
                checkboxes.map(item => (
                    <label key={item.key}>
                        {item.name}
                        <Checkbox name={item.name} checked={checkedItems.get(item.name)} onChange={handleChange} />
                    </label>
                ))
            }
        </div>
    );
}
export default Example;

Checkbox:

import React from 'react';

const Checkbox = ({ type = 'checkbox', name, checked = false, onChange }) => {
    console.log("Checkbox: ", name, checked);

  return (<input type={type} name={name} checked={checked} onChange={onChange} /> )
}
export default Checkbox;
