Custom Trigger for Price Update

Great Plugin! We are using an elementor theme that has plus & minus symbols next to the qty box. Clicking the plus & minus symbols changes the qty. Unfortunately this does not trigger a change in the total price.

I dug around a little & found a few ways this type of situation could be resolved. In this particular situation adding these triggers would resolve my specific situation.

	$(document).on('click','#plus_qty',function(){
	calculate_price();	
	});
	
	$(document).on('input','#minus_qty',function(){
	calculate_price();	
	});

Another option would be to put the function outside of the jQuery event so it could be called by could outside your jQuery event. (Probably a really bad idea)

Assign the functions to 1 global so that they can be accessed & triggered by custom code outside the plugin. (Probably a better idea).

Thanks for the great plugin.
