Thanks Matt, that worked great! However, I am creating a new component with my add function. That component is an HBox with various text inputs and a delete button to handle a delete function for that particular HBox. How do I get the newly created component to recognize what number it is in the array and to delete itself? Do I need to dispatch the position in the array from the first component, handle it in the 2nd component, call a delete function then dispatch that result back to the 1st component? Or, is there a better way to get this functionality?
