Click on the menu button item checkbox weird behavior

[rochejul]

Hi

When we look to your plunker for the ui-grid menu (http://plnkr.co/edit/?p=preview), we could see the following behavior:

First scenario:

• Click on the menu
• Click on the "col: name" label

The checkbox item has changed (cross)
The associated column disappeared

• Click on the "col: name" label

The checkbox item has changed (check)
The associated column apperead

Second scenario:

• Click on the menu
• Click on the "col: name" icon

The checkbox item has not changed (style check)
The associated column disappeared

• Click on the "col: name" icon

The checkbox item has not changed (check)
The associated column apperead

It seems there is a tiny bug when we click direclty onto the menu item icon

Regards
