$ionicLoading.hide() not working - ionic-framework

Question

I have this Ionic code. The problem is $ionicLoading.hide(); is not hiding the popup. I cant make the "waiting" icon Disappear
function ($scope, $q, $state, $rootScope, $stateParams, $firebaseArray, $window, $ionicLoading) {
var palabras = $rootScope.textAreaOfrecer.replace(/[.#$/]/g,'').toLowerCase().split(' ');
if($rootScope.flag == 1){
return true;
}else{
$rootScope.flag = 1;
}
console.log("0");
$ionicLoading.show();
setMyNewArray().then( function (){
console.log("3");
$ionicLoading.hide();
$rootScope.flag = 0;
console.log("4");
});
function setMyNewArray() {
var deferred = $q.defer();
console.log("1");
Promise.all(
$scope.solicitudes = palabras.map(palabra => $firebaseArray(firebase.database().ref().child("solCompras").orderByChild("palabras/" +
palabra).equalTo(true) ) )
).then( function (){
$scope.solicitudes = multiDimensionalUnique($scope.solicitudes).reduce(function(prev, curr) {
return prev.concat(curr);
});
console.log("2");
deferred.resolve();
});
return deferred.promise;
}
function multiDimensionalUnique(arr) {
var uniques = [];
var itemsFound = {};
for(var i = 0, l = arr.length; i < l; i++) {
var stringified = JSON.stringify(arr[i]);
if(itemsFound[stringified]) { continue; }
uniques.push(arr[i]);
itemsFound[stringified] = true;
}
return uniques;
}
}

I have changed location of show loader and hide loader.. try it once
function ($scope, $q, $state, $rootScope, $stateParams, $firebaseArray, $window, $ionicLoading) {
var palabras = $rootScope.textAreaOfrecer.replace(/[.#$/]/g,'').toLowerCase().split(' ');
if($rootScope.flag == 1){
return true;
}else{
$rootScope.flag = 1;
}
console.log("0");
setMyNewArray().then( function (){
console.log("3");
$rootScope.flag = 0;
console.log("4");
$ionicLoading.hide(); //use hide here
});
function setMyNewArray() {
$ionicLoading.show(); //use loader here.
var deferred = $q.defer();
console.log("1");
Promise.all(
$scope.solicitudes = palabras.map(palabra => $firebaseArray(firebase.database().ref().child("solCompras").orderByChild("palabras/" +
palabra).equalTo(true) ) )
).then( function (){
$scope.solicitudes = multiDimensionalUnique($scope.solicitudes).reduce(function(prev, curr) {
return prev.concat(curr);
});
console.log("2");
deferred.resolve();
});
return deferred.promise;
}
function multiDimensionalUnique(arr) {
var uniques = [];
var itemsFound = {};
for(var i = 0, l = arr.length; i < l; i++) {
var stringified = JSON.stringify(arr[i]);
if(itemsFound[stringified]) { continue; }
uniques.push(arr[i]);
itemsFound[stringified] = true;
}
return uniques;
}
}
