How to run a directive in angular after receiving a value from the server?

Question

JavaScript

Send to directive
<div index index="vm.rating"></div>
Receive to directive

scope:{
                index: '='
            },
            link: function(scope, element, attr) {
                console.log(scope.index); //возвращает undefined, потому что запрос не успевает отработать 
            }

how to make the directive run only when the request returns data in vm.rating ?

Answer 1

<div index index="vm.rating" ng-if="vm.look_Ma_Iam_Ready"></div>

Answer 2

You cannot duplicate attributes. Remove one index.

<div index="vm.rating" ng-if="vm.look_Ma_Iam_Ready"></div>
