React - Create a Controlled Input

JavaScript
1

Tell us what’s happening:

Hello freeCodeCamp,
I am bit stuck with this one, I don’t understand the last test:
3. Typing in the input element should update the state and the value of the input, and the p element should render this state as you type.
Can you help me?

Your code so far

class ControlledInput extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      input: ''
    };
    // Change code below this line
  this.handleChange = this.handleChange.bind(this);
    // Change code above this line
  }
  // Change code below this line
  handleChange(event) {
    this.setState(state => {
      input: event.target.value
    })
  }
  // Change code above this line
  render() {
    return (
      <div>
        { /* Change code below this line */}
        <input value={this.state.input} onChange={this.handleChange} />
        { /* Change code above this line */}
        <h4>Controlled Input:</h4>
        <p>{this.state.input}</p>
      </div>
    );
  }
};

Oh, I find the solution by myself, the handleChange() function is wrong. I have to remove state => on it and all tests passed
