How to call a function in angularjs?

Question

Angular

app.controller("test", function($scope, $http){
  $scope.getTag = function(){
     $http.get('/api/v0/todos/tags').success(function(data){
       return data.items; // данные
     });		
  }
  
  $scope.showTasks = function (){
    var tag = $scope.getTag(); // что-то не так
    console.log(tag);		
  };
});

When I call showTasks in the template {{showTasks()}} repeatedly makes a call, it gives an error. What am I doing wrong in the request?

10 $digest() iterations reached. Aborting!
Watchers fired in the last 5 iterations: []
Here's an error for you. You call an asynchronous function many times, before one has time to fire, you call the second and so on, because of this, angular tries to call the digest cycle every time and stumbles upon the fact that it is already running.
To do this, you need to call asynchronous functions not so often and many times, read about debounce (to call a function, for example, once every half a second)
