Get button label using 'getElementAt()'

Question

Hello!
I have 100 buttons in a container and I'm trying to get label of one of them. The problem: getElementAt() returns IVisualElement and it doesn't have label property. It returns other properties right.
This line: if (cellContainer.getElementAt((row - 1)*10 + col-1).label == 'X')

Try either of the following and tell me if it works
1. Button(cellContainer.getElementAt((row - 1)*10 + col-1)).label=='X'
2.  var button:Button=new Button()
     button=cellContainer.getElementAt((row - 1)*10 + col-1) as Button
     if (button.label == 'X')
