Is there a way to dynamicly change price using js

[Williamtidana]

I have recently made a custom feature using html, css and javascript. The feature is bassicly a canvas that you can change the size of with two sliders. I am saving the dimensions and calculating a price in the js. I have managed to have a button that saves the dimensions for the canvas and adds it as 'notes' to the order. However is there a way to use my calculated price form js to change the price at checkout?

I have tried using some apps but they have not worked with my custom feature. Is there any good solution to this?
