Glowfilter not working on textfiled?

programming flash
1

I have four instances of a movieclip (consisted of a textfield) on stage with given names btn1,btn2,btn3,btn4.
The issue is I cannot get the GlowFilter work on ROLL_OVER event Listener.


import com.greensock.*; 
import com.greensock.easing.*;

var buttons_array:Array = [btn1,btn2,btn3,btn4];

var previousBtn = MovieClip(buttons_array[0]);
previousBtn.mouseEnabled = false;

TweenMax.to(previousBtn, 0, {tint:0xCAB16F});

for (var i:Number=0; i<buttons_array.length; i++) {
    buttons_array*.id = i;
    buttons_array*.mouseChildren=false;
    buttons_array*.buttonMode=true;
    buttons_array*.addEventListener(MouseEvent.ROLL_OVER, onRollover, false, 0, true);
}
function onRollover(e:MouseEvent):void {
    e.target.addEventListener(MouseEvent.ROLL_OUT, onRollout, false, 0, true);
    e.target.addEventListener(MouseEvent.CLICK, buttonClicked, false, 0, true);
    TweenMax.to(e.target, 1, {glowFilter:{color:0x91e600, alpha:1, blurX:30, blurY:30}});
	
}
function onRollout(e:MouseEvent):void {
    TweenMax.to(e.target, .1, {tint:null});
	
}
function buttonClicked(e:MouseEvent):void {
    var currentBtn = MovieClip(e.target);
    previousBtn.addEventListener(MouseEvent.ROLL_OVER, onRollover, false, 0, true);
    currentBtn.removeEventListener(MouseEvent.ROLL_OUT, onRollout);
    currentBtn.removeEventListener(MouseEvent.CLICK, buttonClicked);
    TweenMax.to(currentBtn, .1, { tint:0xCAB16F});
    TweenMax.to(previousBtn, .1, {tint:null});
    previousBtn.mouseEnabled = true;
    currentBtn.mouseEnabled = false;
    previousBtn = currentBtn;
}

Can sb see what’s wrong?
