I know you can unbind a $watch like this:

var listener = $scope.$watch(tag, function () {});

// ...

listener(); // would clear the watch

but can you unbind the watch within the watch function declaration. So after the watch gets executed once, it unbinds itself? Something like:

$scope.$watch(tag, function () {

    unbindme()

});

you can just do it the same way you already do, call the deregistration inside your function:

var unbind = $scope.$watch(tag, function () {

    // ...

    unbind();

});
