Create a dynamic text list

I wanted to create a running list based on button functions for a menu I am designing.
A function for hotdog purchase is below.

function hotdog(evt:MouseEvent) {
    var responderhotdog = new Responder(insertHotdog_Result);
    //Call the insert titles function"Purchase.insertPurchase", responderhotdog, "", "Customer", "Name", "101", "1", "1", "4", "Hot Dog");
   ** foodorder.text = "Hot Dog";**

foodorder.text will put that one word into the text field, but I wanted a running list of the items, and then a button to clear it. Any ideas?
