<span className="close" onClick={this.props.onclick}><u>Close</u> X</span> // basically this is what you want no? const onclick = () => { handleClose(); doIsChecked(); }; If you need the event then you can pass it from the onclick function to the handleClose or doIsChecked
Update:
Actually the script above is more general. In your case it would probably look like this:
<span className="close" onClick={onclick}><u>Close</u> X</span> .
const onclick = () => { this.props.handleClose(); doIsChecked(); };
