ActionScript 3.0 :: Listen For Objects Created By AddChild?

i created a "for" function who ´ll display an X number of buttons with addChild, and give a name for each using button.name = "name" + variable but later if I want to listen for the buttons using their name don´t work, already know that there is getChildByName so i tried but give me the same error who tells that there no object with that name.My question is, how i can listen for the objects created if i already have a name for each one of them? here is the code im doing.
 
for(var i:int = 1; i <6;i++){var miBoton:boton = new boton();var miTexto:TextField = new TextField();miBoton.x = i * miBoton.width + (i* 10);miBoton.y = 20;addChild(miBoton);miBoton.name = "boton" + i;miTexto.text = "hi";miBoton.addChild(miTexto);trace(miBoton.name);trace(miBoton.parent);}
