You'll find all the details you need to accomplish this in the ADF Developer's Guide for Forms/4GL Developers on the ADF Learning Center at http://www.oracle.com/technology/products/adf/learnadf.html.
Section "8.3 Adding a Custom Service Method" explains how to add a service method to your application module.
Section "7.8.3 Example of Creating a New Service Request" shows the code required to create a new row in a view object.
Then you would just use the setAttribute() method on the target row to set the desired attributes to the new values based on the values from the source row.
Section "8.4.1 How to Publish Custom Service Methods to Clients" describes how you would publish your service method to clients.
Section "10.3.3 How the Data Model and Service Methods Appear in the Data Control Palette" describes where to look to see your published client methods in the data control palette to drop them as a button on a page.
Section "4.5 Understanding the Active Data Model" explains why the UI will automatically refresh to display the changes you've made in your application module method when it's invoked.
