Calling a function when ng-repeat has finished

Question

What I am trying to implement is basically a \"on ng repeat finished rendering\" handler. I am able to detect when it is done but I can\'t figure out how to trigger a functi

A solution for this problem with a filtered ngRepeat could have been with Mutation events, but they are deprecated (without immediate replacement).

Then I thought of another easy one:

app.directive('filtered',function($timeout) {
    return {
        restrict: 'A',link: function (scope,element,attr) {
            var elm = element[0]
                ,nodePrototype = Node.prototype
                ,timeout
                ,slice = Array.prototype.slice
            ;

            elm.insertBefore = alt.bind(null,nodePrototype.insertBefore);
            elm.removeChild = alt.bind(null,nodePrototype.removeChild);

            function alt(fn){
                fn.apply(elm,slice.call(arguments,1));
                timeout&&$timeout.cancel(timeout);
                timeout = $timeout(altDone);
            }

            function altDone(){
                timeout = null;
                console.log('Filtered! ...fire an event or something');
            }
        }
    };
});

This hooks into the Node.prototype methods of the parent element with a one-tick $timeout to watch for successive modifications.

It works mostly correct but I did get some cases where the altDone would be called twice.

Again... add this directive to the parent of the ngRepeat.
