How to force RSForm to take into account the data of the select, which is changed through the slider?

Question

JavaScript

There is a site on Joomla, the RSForm component is used, which can perform calculations depending on the values ​​\u200b\u200bselected in the form. This form has a select with three values, each of which affects the final price. The client needed to replace the select with a slider at the front, and for lack of it in RSForm, he had to use a JS script that generates it. As a result, I have a select and a slider, changing one element causes a change in the other, it would seem that everything is fine, but when using the slider, the price value does not change. At the same time, if you use the select, then the price changes correctly. Why is this happening?
