I am trying following code but somehow componentDidCatch is not working

App.js 
import React from 'react';
import Header from './Header';

class  App extends React.Component {

  state = {
    hasError :false
  };

  componentDidCatch() {
    console.log('Error Caught');
    this.setState({hasError:true});
  }

  render () {

    if(this.state.hasError) 
      return (<header><h1>Oops! Something went wrong</h1></header>);
    else
      return (

        <div className="container">
          <Header />
          </div>
    );
  }

}
export default App;
Header.js 
import React from 'react';

class Header extends React.Component{


  aaa = {}
  accessIssue = () => {let a = (this.aaa.aaa.a)}; //Error will be thrown

  render () { 
    return (
      <header>
          <button onClick={this.accessIssue}>Click To Fail</button> // On Click of this button..
      </header>
    )
    }
}

export default Header;
