Problems with Create a Controlled Input

JavaScript
1

Tell us what’s happening:

Hello people.somebody could tell me what it is wrong in my code because i did all what the challenge asked and it is working but i can not pass the challenge.
that is what i dont get:
“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.”

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({input:event.target.value });
  }
  // change code above this line
  render() {
    return (
      <div>
        { /* change code below this line */}
        <input onChange={this.handleChange}/>
        { /* change code above this line */}
        <h4>Controlled Input:</h4>
        <p>{this.state.input}</p>
      </div>
    );
  }
};

Make sure you are also giving value attribute to the input and have it equal to this.state.input

Add a value attribute which is equal to the input property of the component’s state.

<input type="text" value={this.state.input} onChange={this.handleChange} />
