Several buttons and dynamic(?) EventListener

Question

Hi everyone,
I place 10 buttons on my stage, name it "b1", "b2", "b3",.. , "b10".
All these buttons should use the same function.
Is it possible to do it dynamically?
var a: Array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
for (var i = 0; i < a.length; i++) {
button = "b" + a[i];
  this[button].addEventListener(MouseEvent.CLICK, onClick_b);
  function onClick_b(pEvt: Event): void {
  my_mc.play();
Only the button "b10" plays the function.
Anyone an idea how to let all the other buttons play this function?
Thank you! C.

Thank you for your answers, this solution works, but I need an array in my project...
Now my buttons are called "bone", "btwo", "three".
var button: String;
button = "b";
var a: Array = ["one","two","three"];
for (var i = 0; i < a.length; i++) {
    button = "b" + a[i];
     button.addEventListener(MouseEvent.CLICK, onClick_b);
function onClick_b(pEvt: Event): void {
    my_mc.play();
But it doesn't work...
