React js onClick can't pass value to method

I want to read the onClick event value properties. But when I click on it, I see something like this on the console: SyntheticMouseEvent {dispatchConfig: Object, dispatchMarker: ".1.1.0.2.0.0:1", nativeEvent: MouseEvent, type: "click", target My code is working correctly. When I run I can see {column} but can't get it in the onClick event. My Code: var HeaderRows = React.createClass({ handleSort:

“ES6 Use an arrow function: return ( <th value={column} onClick={() => this.handleSort(column)}>{column}</th> ); ES5 You can use .bind to pass the parameter you want: return ( <th value={column} onClick={that.handleSort.bind(that, column)}>{column}</th> );”
