How to show and hide $ionicLoding for $ionicModal open and close progress using Ionic Framework

I fond below code for $ionicLoading for page state change on navigation

$scope.$on('$stateChangeStart', function(event, toState, toParams, fromState, fromParams){
   $ionicLoading.show({
     template: '<p>Loading...</p><ion-spinner class="spinner spinner-bubbles"></ion-spinner>' 
  });  
});
$scope.$on('$stateChangeSuccess', function(event, toState, toParams, fromState, fromParams) {
  $timeout(function(){
     $ionicLoading.hide();
  },2000);
});

But it is work only for page state change.

I need for $ionicModal modal popup open and close state.
