The button().add() and button().remove() methods provide the ability to
dynamically add and remove buttons from the list. The button().add() method takes two parameters: firstly the insertion point for where the new button should appear, and secondly a
button definition (which can be an object, a string or a function) and displays that button.
This example shows a button that when activated will add new buttons to the list. These buttons, when activated, will then be removed. Although this example lacks practical utility, it does demonstrate the API methods.

dt.button().add( 1, {
text: 'Button '+(counter++),
action: function () {
this.remove();
}
} );
}
}
]
} );
} );
