How to set defaultProps for function?
<p>Is it possible to set defaultProps for functions? Code below doesn't work. It doesn't like 'this'. I tried 1_ bind defaultProps to 'this', or 2_ bind handleClose to 'this', neither works. I use ES6 class.</p>

<pre><code>SaveDialog.propTypes = {
  note: React.PropTypes.string,
  onCancel: React.PropTypes.func,
  onSave: React.PropTypes.func,
  onEditChange: React.PropTypes.func
};

SaveDialog.defaultProps = {
  note: '',
  onCancel: {this.handleClose},
  onSave: {this.handleClose},
  onEditChange: {this.handleChange}
};
</code></pre>
