How to change loading-container classname of $ionicloading?

Is this possible?

Using this now.

  $ionicLoading.show({
      template: '<div class="preload-wrapper" ng-show="removeAfterLoad"> '+
      '<p>Please wait, the page is being loaded </p> '+
  '</div>',
      duration: 2000
      // noBackdrop: true
    });

It gives me the HTML:

<div class="loading-container">
   <div class="preload-wrapper" ng-show="removeAfterLoad"> 
   </div>
</div>

I want to change the loading-container classname or add a new classname (so it’s about the parent classname), but this is not working for me.

Is there a way to do this at all?
