Stores' change listeners not getting removed on componentWillUnmount?

Question

I am coding a simple app on reactjs-flux and everything works fine except I am receiving a warning from reactjs telling me that I am calling setState on unmounted components

Answer 1

I decided it so

class Tooltip extends React.Component {
    constructor (props) {
        super(props);

        this.state = {
             handleOutsideClick: this.handleOutsideClick.bind(this)
        };
    }

    componentDidMount () {
         window.addEventListener('click', this.state.handleOutsideClick);
    }

    componentWillUnmount () {
         window.removeEventListener('click', this.state.handleOutsideClick);
    }
}
