Bitrix core.js does not process a programmatically created event?

Question

JavaScript

Good afternoon, I can't figure out why Bitrix core.js does not process the select change event.
The idea was this - after selecting the size of the product in the filter and going to the product card, automatically substitute the desired value in the select, through which the size is selected (sales offer), so that the price is automatically recalculated.
All the necessary parameters are received, select selects the desired option, but the price is not recalculated.
Here is how I tried to implement it

$(document).ready(function(){   					
var dropdown = $(".select_sku"); 
$("option", dropdown).each(function(){
var data_val = $(this).attr("data-onevalue"); 
if(data_val  == $(".filter_id").text()	) {		
var f_val =	$(this).val();	
$(".select_sku").val(f_val).trigger("change");
}	
});					
});

I would be very grateful for any hint.

Answer 1

.trigger("change");

This is jquery.
Raise a native event.
