ng-class condition changes, but not updating classes

Instead of

ng-class="{'active': {{selectedCat == cat.id}}}"

use

ng-class="{active: selectedCat == cat.id}"

Replace:

ng-class="{'active': {{selectedCat == cat.id}}}"

With:

ng-class="{'active': selectedCat == cat.id}"

You never need to nest those curly braces like that, in Angular.

Have a look at the ng-class documentation for some more examples.

Hi i'm also facing the same problem. i solved the problem by the way instead of assigning the value directly to ng-class, call the separate method and return the value.

ex :

ng-class="getStyleClass(cat)"

$scope.getStyleClass = function(cat)  {   
      return "active: selectedCat == cat.id";  
}

roughly i coded. please change the method as per your requirement.
