EVENT_ITEM_CHANGE not send text value

I have a project with:

- 1 Page with name "Eventi"

- 4 EditBox with name in page

- 1 Sound with name "beep.wav"

I need play a sound when text property of one item change and text is "1".

I write in JS this code

var Eventi;

IR.AddListener(IR.EVENT_START, 0, function()

{

Eventi = new Alarm();

});

function Alarm()

{

var ItemList = ["Item 4","Item 1","Item 2","Item 3"];

var Page = IR.GetItem("Eventi");

for(i=0;i<ItemList.length;i++)

{

IR.Log("Generazione evento item "+ItemList[i]);

IR.AddListener(IR.EVENT_ITEM_CHANGE, Page.GetItem(ItemList[i]),function (text)

{

if(text = "1")

{

IR.PlaySound('Alarm.mp3');

}

});

}

};

I run this code with some Log istruction and i see that when i change text on the object, the variable "text" in JS is always "undefined".

This is a bug or I wrong something?
