Updates to the template of an AngularJS directive are reflected, but the link remains unchanged

I'm encountering an issue with a directive that has 2-way data binding scope. Here's the code snippet:

app.directive('channelStar', function() {
  return {
    restrict: "E",
    template: 'This is working as expected : {{count}}',
    scope: {
      count: '='
    },
    link: function(scope, element, attrs) {
      // The count value displays in the template but isn't updating here
      // It seems to be logging the old scope value
      console.log(scope.count);
    }
  }
});

In my routing template (using ui-router and nested states):

<channel-star count="selectedChannel[0].channel_dir_members"></channel-star>

Controller:

httpService.request(...).then(function(result){
    $scope.selectedChannel = result.data;
    $rootScope.selectedChannel = result.data;
    // $scope.$applyAsync();
    // $rootScope.$applyAsync();
})

Any suggestions on how to address this issue?

Answer №1

Monitoring a function will only execute once. To work with its updated value, you can utilize scope.$watch to observe the changes in count.

scope.$watch('count', function(newValue, oldValue) {
  if(newValue){
     //do something
  }
}, true);     // The parameter 'true' here is used for deep object comparison, it is not needed when dealing with strings only

Answer №2

Another option is to incorporate the following code into your directive: scope.$apply(function() {});
