Copy input value into another dynamically created input

Question

I'm creating a page for an alt currency where a business owner can set prices for various products. The suggested exchange rate is $10 to 1 Current. I want the user to input a dollar price and have the Current input automatically populate at 1/10 the amount in the dollar input.

I have this working for the first set of inputs. However, the user can also add more product inputs by clicking a button. My keyup function does not work for these dynamically created inputs. Any ideas?
