pre remove middleware not firing

I'm using mongoose and trying to cascade a delete but unfortunately my pre remove middle ware is not firing for some reason.

  var presentationSchema = new Schema({
    id: Number,
    title: String,
    pdfURL: String,
    created_at: Date,
    updated_at: Date,
    slides: [{
      type: Schema.Types.ObjectId,
      ref: 'Slide'
    }]
  });

  presentationSchema.pre('remove', function(next) {
    console.log("delete slides" + this._id);
      next();
  });

  // the schema is useless so far
  // we need to create a model using it
  var Presentation = mongoose.model('Presentation', presentationSchema);


  // make this available to our users in our Node applications
  module.exports = Presentation;

Maybe you get hooked by this mongoose "feature" :

Note: There is no query hook for remove(), only for documents. If you set a 'remove' hook, it will be fired when you call myDoc.remove(), not when you call MyModel.remove(). Note: The create() function fires save() hooks.

Your pre('remove',...) middleware will be fired when you call myPres.remove() not when calling remove function from the model like Presentation.remove()
