[flexcoders] Adding a button Icon

[criptopus]

// Add TLink To Issue Box
issButArray.push(new Button());
issButArray[i].icon="@Embed(source='icons/more.gif')";
issHbxArray[i].addChild(issButArray[i]);

Error :

Cannot create property icon on mx.controls.Button

how do I set a buttons icon programatically?
