Can we delay rendering in angularjs until all variables get required values from callbacks

I have shared angularjs code. There IsShopToShowTerminated is always undefined and doesn’t depict the required value. I think problem is because, it renders first and then value of the IsShopToShowTerminated is changed. After search I am getting more and more confused. $scope.IsShopToShowTerminated = function(shopTerminationDate) { setTimeout(function() { debugger; if ($scope.IsTerminated($scope.viewCompany.TerminationDate)) { return true; } else { return $scope.IsTerminated(shopTerminationDate); } }, 0); } <td ng-init=”isTerminatedValue = IsShopToShowTerminated(shop.TerminatinonDate)”> {{isTerminatedValue}} <div ng-show=”isTerminatedValue”> <i class=”fa fa-circle text-danger”></i> <small>Terminated</small> </div> […]

Background For the application I’m working on, I have a […]
