Reset text box values

[smithcgl9043167]

Hello! How do I reset the text box information when I click the resize buttons again to either feed or shrink after clicking the reset button? What's missing? Thanks!

app.purge (PurgeTarget.HISTORYCACHES);
dlg = new Window("dialog");   dlg.text = "Resize Layer"; 
    scala = 100; 
    dlg.preferredSize.width = 200;   dlg.preferredSize.height = 80; 
    dlg.orientation = "column";  dlg.alignChildren = ["center","top"]; 
    group1 =  dlg.add("group");   group1.orientation = "row"; 
    group1.alignChildren = ["left","center"]; 
    t1 = group1.add("statictext");   t1.text = "Resize:"; 
    t2 = group1.add("edittext");  t2.text =  " " + scala + "%"; 
    be = group1.add("button");  be.text = "R(+)"; 
    br = group1.add("button");   br.text = "R(-)"; 
    bt = group1.add("button");  bt.text = "Reset"; 
    be.onClick = function() {
        scala += 5;  t2.text = "" + scala + "%"; resizerLayer(105, 105);
        app.refresh();
     }
     br.onClick = function() {
       scala -= 5;  t2.text = "" + scala + "%"; resizerLayer(95, 95);
       app.refresh();
     }
     bt.onClick = function(){   
        t2.text = " " + "100" + "%"
        activeDocument.activeHistoryState = activeDocument.historyStates [1];
        app.refresh();
      }
dlg.show();
function resizerLayer(w,h){
    var startRulerUnits = app.preferences.rulerUnits; 
    var strtTypeUnits = app.preferences.typeUnits;  
    app.preferences.rulerUnits = Units.PERCENT;  
    app.preferences.typeUnits = TypeUnits.PIXELS;  
    app.activeDocument.activeLayer.resize(w,h, AnchorPosition.MIDDLECENTER);
    app.preferences.rulerUnits = startRulerUnits;  
}

Add:

scala = 100;

somewhere in the bt.onClick = function()
