React - _this2.SetState is not a function

Try this:

class SearchBar extends Component {
  constructor(props) {
    super(props);
    this.state = { term: '' };
    this.setInputState = this.setInputState.bind(this);
  }
  
  setInputState(event) {
    this.setState({ term: event.target.value });
  }

  render() {
    return (
      <div className="search-bar">
        <input value={this.state.term} onChange={this.setInputState} />
        The value of input is: {this.state.term}
      </div>
    );
  }
}


you have to bind {event => this.SetState(event.target.value)} function to component this. problem is your onChange function not running your component this context

code should look something like this 

const onChange = (event) => { this.setState({term:event.target.value}) }

 <input value={this.state.term} onChange={onChange.bind(this) />
