When I have multiple divs like...

```
<div class="parent">
    <button class="children">click</button>
</div>

<div class="parent">
    <button class="children">click</button>
</div>

```

(Normally, I add this html by using jQuery)

I will my buttons will work only one time per one button

```
$('.parent').on('click', '.children', function () {
    alert('test');
    $(this).off('click','.children');
});

```

I have no idea how to `.off()` click event each button ?

PS : jQuery 1.9+

PS : I dont want to cancel all button events
