access widget size and position with custom item map

[capitanjacksparrow]

Hi, I'm using a custom item map to draw widgets on my dashboard:

$scope.customItemMap = {
sizeX: 'widget.size[0]',
sizeY: 'widget.size[1]',
row: 'widget.position[0]',
col: 'widget.position[1]'
};

Is there a way to use the stop callback of the resizable (or draggable) property to get the new widget size or position? I found issue #213 addressing this problem, but the discussion wasn't helpful for me.
