TextInput never gets the focus

I am trying to have a TextInput inside a button, but it seems that my button intercept all mouse events before my TextInput.

Basically I have a class BaseButton like that :

public class BaseButton extends Sprite
{
    [...]
        public function addMouseListeners( target : InteractiveObject = null ) : void {
            if ( !target ) target = this;
            target.addEventListener(MouseEvent.ROLL_OVER, mouseOverHandler, false, 0, true);
            target.addEventListener(MouseEvent.ROLL_OUT, mouseOutHandler, false, 0, true);
            target.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler, false, 0, true);
            target.addEventListener(MouseEvent.MOUSE_UP, mouseUpHandler, false, 0, true);
        }
    [...]
}

The class where I want to put the TextInput extends BaseButton

public class AddFilterDropDownListItem extends BaseButton {
    private var _input:TextInput;

    public function AddFilterDropDownListItem() {
        super();
    }

    override protected function setupAssets():void {
        _input = new TextInput();
        _input.height = 40;
        _input.width = 240;
        this.addChild(_input);
        _input.appendText("Add..");
    }
}

I cannot edit the TextInput, the click event seems to be captured by BaseButton. I don't understand why, as a child of BaseButton, my TextInput hasn't the priority?

I can resolve my problem by adding the TextInput by adding it to the parent :

override protected function setupAssets():void {
    _input = new TextInput();
    _input.height = 40;
    _input.width = 240;
    parent.addChild(_input);  //<------ dirty solution
    _input.appendText("Add..");
}

Can you explain me why it is failing? And how can I resolve it cleanly?

PS: I cannot change the architecture of the project. My class has to extend BaseButton and I cannot change BaseButton.

The BaseButton class probably has mouseChildren set to false, which prevents any nested DisplayObjects from receiving mouse events. Everything should work as expected, if you set mouseChildren = true; on your derived class.
