I am not sure you can do that. You may want to find a workaround using

window.addEventListener('beforeunload', myFunction);

You can override the remove method from Backbone.View as:

remove: function () {

    this.trigger('view:unload'); //Whatever event name

    Backbone.View.prototype.remove.call(this); //Important
},

It is important to call the original function to delete correctly the view.
