Add dynamic angular attributes to dom element - angularjs

Question

I have an ApplicationController that runs over my dynamic controller
This Application controller has an array that are my App-bar actions.
Well, every dynamic controller i have inherit the ability to change this array, once its on $scope.headers.actions;
What I'm trying to do right now is to create a directive where i'll be able to add angular attributes (ng-class, ng-if, etc...) dynamically where this attributes definition will come from $scope.headers.actions[...].attributes
Now my directive is:
app.directive('ngDynamicAttrs', ['$compile',function ($compile) {
return {
scope: { list: '=ngDynamicAttrs' },
//priority: 1001,
//terminal: true,
link: function (scope, elem, attrs) {
for (attr in scope.list) {
attrs.$set(attr, scope.list[attr]);
//elem[0].setAttribute(attr, scope.list[attr]);
//elem.attr(attr, scope.list[attr]);
}
$compile(elem)(scope);
}
};
}]);
My html is:
<ul class="actions">
<li class="action" ng-repeat="action in header.actions.pool" ng-click="action.events.click()" ng-dynamic-attrs="action.attributes" id="{{action.id}}">
<i ng-if="action.icon" class="icon fa {{action.icon}}"></i>
{{action.name}}
</li>
</ul>
And my action object is :
$scope.header = {
actions: {
pool: [],
clear: function (actions) {
$scope.header.actions.pool = [];
},
set: function (actions) {
$scope.header.actions.clear();
for (i in actions) {
$scope.header.actions.add(actions[i].id, actions[i].name, actions[i].icon, actions[i].events, actions[i].items, actions[i].attributes)
}
},
add: function (id, name, icon, events, items, attributes) {
$scope.header.actions.pool.push($scope.header.actions.create(id, name, icon, events, items, attributes));
},
remove: function (id) {
for (i in $scope.header.actions.pool) {
if ($scope.header.actions.pool[i].id == id) delete $scope.header.actions.pool[i];
}
},
create: function (id, name, icon, events, items, attributes) {
return { id: id, name: name, icon: icon, events: events, items: items, attributes: attributes };
}
}
}
Note: I'm not even considering the events right here because it's not a big deal once i can easily use normal dom events.
