Angular.js trigger ng-show in callback

Question

I tried calling ng-show by editing the scope in the setTimeout function. setTimeout here is a placeholder for the database query callback.

index.html

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.15/angular.min.js"></script>

<script src="script.js"></script>

<div ng-controller="c1">

    <div ng-show="{{show}}"  >

        test it

    </div>

</div>

script.js

var amTestNgShow = angular.module('amTestNgShow',[]);

amTestNgShow.controller('c1', ['$scope', function($scope) {

    // this works: $scope.show = true;

    setTimeout(function(){

        $scope.show = true; // works not

        // does not help: $scope.$apply();

    }, 1000)

}]);

how can this be done in setTimeout? THX!

Update. As explained above, setTimeout is not a problem, it is only used to create a reproducible stack question. In my project, I created a service:

amProject1.service('asBasic', ['$http', '$q', function($http, $q){

    var asBasic = {};

    asBasic.docName = '';

    var doc = {};

    asBasic.get = function(id){

        var deferred = $q.defer();

        $http({method:'GET', url: '/' + this.docName + '/' + id})
            .success(function(data, status, headers, config){

                if(data === undefined){

                    deferred.reject("The requested " + asBasic.docName + " was not found.")

                }

                doc = data;
                deferred.resolve(doc);

            })
            .error(function(data, status, headers, config){

                deferred.reject(status);

            })

       return deferred.promise;

    }


    return asBasic;

}]);

use it like

amProject1.controller('acDoc1', ['$scope', '$routeParams', 'asBasic', function($scope, $routeParams, asBasic){

    asBasic.docName = 'doc1';

    // this works: $scope.show = true;

    asBasic.get($routeParams._id)
        .then(function(data){

            $scope.doc1 = data;

            $scope.show = true; // works not

            // does not help: $scope.$apply();

            // ...

        }
        // ...
