When do we know the actual width of an element in Angular?

Question

I\'m tring to create a directive that will center a div.

So far, I have this code:

app.directive(\"setcenter\", function () {
    return {
        scope:

James' answer led me to:

app.directive('measureInto', function () {
        return {
            restrict: 'A',
            link: function (scope, element, attrs) {
                scope.$watch(function() {
                    return element[0].clientWidth;
                }, function(value){
                    scope[attrs.measureInto] = element[0].clientWidth + 10;
                });
            }
        };
    });

So, at runtime, I add this and assign into whatever scope variable I want the width of the element I'm looking for
