Add Label To A Form Dynamically

I'm using this to add a label to a form. I'm adding new form inputs so the user can add links:

var obj = document.createElement("label");
obj.setAttribute("for", "link"); //this seems not to work in IE6

var myText = document.createTextNode("Label name");
obj.appendChild(myText);
document.getElementById("Links").appendChild(obj); //there's a void div called "Links" in the html
obj = document.createElement("input");
obj.setAttribute("type", "text");
obj.setAttribute("name", "link");
obj.setAttribute("id", "link");


In the html I use a link that calls the function to add dynamically the input and label.

It's working ok in Firefox... I mean, when you click on the label, the input get the focus (just as a normal html label tag).

But it does not work in IE6... Does anybody knows if there's some change to make it work in IE6?
