Combo product and play value in inputText

Question

I am developing a DOCUMENT registration with parameters such as Material, Name and other data. And how it will work, before performing a normal PRODUCT registration with parameters of Material and Name and on the registration screen of DOCUMENT I want to open a combo like this code "Material" and choosing it, will be automatically played the name in the inputText NAME field.

I created the combo and I can select.

How to perform this function, something from JSF, Javascript? They told me about valueChanceListener, but tmb do not know how it would be?
