AngularJS - ngShow is not working -


my view written follows:

<ul class="commentslist cf">         <li class="cf" ng-repeat="(key,comment) in activity.comments">           <div class="comment">{{comment.name}}             <div class="buttons" ng-show="isposteduser(activity.$id, key, currentuser)">               <button class="btn btn-delete tooltip"                 confirmation-needed = "are sure want delete activity?"                 ng-click="deletecomment(activity.$id,key)">                 <span>delete comment</span></button>             </div><!-- buttons -->           </div><!-- comment -->         </li>             </ul>

in controller associated view, there function called: 

$scope.isposteduser = function(actid, key, user) { var refcomment = new firebase(firebase_url + "users/" + $scope.whichuser + "/activities/" + actid +   "/comments/" + key); var commentobj = $firebase(refcomment).$asobject(); commentobj.$bindto($scope, "data").then(function() {   return $scope.data.giver === user.$id; });

};

the purpose of function display delete button isposteduser evaluates true. tested , evaluate true, still not display button. idea why?

let's rewrite function proper indentation:

$scope.isposteduser = function(actid, key, user) {     var refcomment = new firebase(firebase_url + "users/" + $scope.whichuser + "/activities/" + actid + "/comments/" + key);     var commentobj = $firebase(refcomment).$asobject();     commentobj.$bindto($scope, "data").then(function() {         return $scope.data.giver === user.$id;     }); };

now, can see function doesn't return (which means returns undefined, falsy).

the return statement code contains returns callback passed then() function. statement executed asynchronously, after isposteduser() has returned.
