onToggle callback function doesn't fire in LeftNav

[fortunebubble]

I was using Material-UI LeftNav and implemented it as follow

<LeftNav ref="leftNav"menuItems={MenuItems} / >

MenuItems = [
  { text: 'A', iconClassName: 'fa fa-search' },
  { text: 'B', iconClassName: 'fa fa-pencil-square-o' },
  { text: 'C', iconClassName: 'fa fa-star' },
  { text: 'D', onToggle: function(){console.log('toggled')} }
];

the strange thing is the icon for each item got loaded correctly, but the onToggle function never get fireback, anyone have any idea why? Thanks
