我想用react useState()添加数组的用户输入对象，当我发送它时，它不会更新问题？

import React, { useState } from 'react';

const MyComponent = () => {
  const [userInputs, setUserInputs] = useState([]);

  const handleInputChange = (event, index) => {
    const { name, value } = event.target;
    const updatedInputs = [...userInputs];
    updatedInputs[index] = { ...updatedInputs[index], [name]: value };
    setUserInputs(updatedInputs);
  };

  const handleSubmit = () => {
    // 在这里发送用户输入的对象
    console.log(userInputs);
  };

  const addUserInput = () => {
    setUserInputs([...userInputs, {}]);
  };

  return (
    <div>
      {userInputs.map((input, index) => (
        <div key={index}>
          <input
            type="text"
            name="name"
            value={input.name || ''}
            onChange={(event) => handleInputChange(event, index)}
          />
          <input
            type="text"
            name="email"
            value={input.email || ''}
            onChange={(event) => handleInputChange(event, index)}
          />
        </div>
      ))}
      <button onClick={addUserInput}>添加用户输入</button>
      <button onClick={handleSubmit}>发送</button>
    </div>
  );
};

export default MyComponent;
