title: React - setState on input field not working
body: <p>I seem to be missing something, why is the setState not working for me?!
  If i pull the initial state into value of the text input field to make it controlled, the setState does not work for me...what am I doing wrong? </p>
  
  <pre><code>      class Module extends Component {
            constructor() {
                super()
  
                this.state = {
                    text: 'text'
                }
  
                this.handleInputChange = this.handleInputChange.bind(this)
            }
  
            handleInputChange(event) {
                console.log('handle input change')
                this.setState = ({
                    text: 'new state: ' + event.target.value
                })
                console.log(event.target.value)
            }
  
            render() {
                return (
                    &lt;div&gt;
                        &lt;input
                            type="text"
                            value={ this.state.text }
                            onChange={ this.handleInputChange }
                        /&gt;
                    &lt;/div&gt;
                )
            }
        }
  
        export default Module
