init focus directive angular js

ngInitFocus.js

angular.module('app', []).directive('ngInitFocus', function() {
    var timer;
    
    return function(scope, elm, attr) {
        if (timer) clearTimeout(timer);
        
        timer = setTimeout(function() {
            elm.focus();
        }, 0);
    };
});

Must be: elm[0].focus()
Even more useful if renamed "autofocus" since it would then be just like page reloads.
