gistfile1.js

import React, {Component, PropTypes} from "react"

class MyComponent extends Component {

  static propTypes = {
    onClick: PropTypes.func,
  }

  handleClick(event) {
    const {onClick} = this.props
    if(onClick) {
      onClick(event)
    }
  }

  render() {
    const {children} = this.props
    return (
      <button onClick={::this.handleClick}>
        {/* here, the `handleClick` method is bound to `this`,
            which is MyComponent instance. */}
        {children}
      </button>
    )
  }
}
