D3 tween does not work inside angular - angularjs

Question

I'm working on this example:
http://bl.ocks.org/mbostock/7607535
I wrapped this into a directive. For some reason, the tween method does not get fired.
var transition = d3.transition()
.duration(d3.event.altKey ? 7500 : 750)
.tween("zoom", function(d) {
var i = d3.interpolateZoom(view, [focus.x, focus.y, focus.r * 2 + margin]);
return function(t) { zoomTo(i(t)); };
});
Is tween incompatible with angular ? Any idea where I should start looking ?

Answer 1

I made a small fiddle from the above http://bl.ocks.org/mbostock/7607535.
I have incorporated the d3 svg component via directive and the tween works perfectly.
var app = angular.module('myApp', []);

Hope this helps!

Answer 2

The root of the problem was datejs. Once I removed it, D3 transitions work fine.
