The most reliable way (right now with v1.0) to sync a callback with the end of the animation or transition is to use setTimeout. First you should set both the duration of the animation and the duration of the CSS transition to the same value. The default CSS and plugin option is already set for 0.8 second. Here's how to change them:

var isoTime = 400;

$('#container').isotope({
  // options...
  // set animation duration
  animationOptions: {
    duration: isoTime
  }
})

And in your CSS for CSS transitions:

.isotope,
.isotope .isotope-item {
-webkit-transition-duration: 0.4s;
-moz-transition-duration: 0.4s;
/* -o-transition-duration: 0.4s;*/
transition-duration: 0.4s;

}

Then you can use setTimeout to trigger the function after the designated time:

var hollaback = function(){
  // hot shiz here..
};

setTimeout( hollaback, isoTime );

If your Isotope layout is resizable with the window, you'll need to bind the setTimeout fun to smartresize

$(window).bind('smartresize', function(){
  setTimeout( hollaback, isoTime );
});

This would be very useful for adding some custom functionality. We're finding that the setTimeout method is a little unreliable as far as timing within larger data sets. If our timeout is set equal to the animation duration, sometimes our function is being triggered before the isotopes are done animating.

Callbacks are a go. Take a look: http://isotope.metafizzy.co/tests/callbacks.html From the docs:

$('#container').isotope({ filter: '.my-selector' }, function( $items ) {
  var id = this.attr('id'),
      len = $items.length;
  console.log( 'Isotope has filtered for ' + len + ' items in #' + id );
});

Within this callback this refers to the container, and $items refers to the item elements. Both of these are jQuery objects and do not need to be put in jQuery wrappers.

Callbacks should be 100% reliable when using jQuery animation. Callbacks with CSS transitions are not perfect, as its possible to remove transitions from elements and Isotope not be aware of it. Methods have callbacks too.

I've done some testing, but I'm sure I missed some use cases (IE testers wanted), so submit a new issue if you run into bugs.

The callback function doesn't work with jQuery 2.1.1.

It seems that this has been removed, I can't find anything related to it on the site and in the code

Callbacks have been removed from Isotope v2. Use events! They are much more reliable :)
