I have created a label element. I need to add onclick event to that...

function a(me) {

    var d=document.createElement(label);

    d.id=me.id;

    d.onClick=a(10);

    d.innerHTML=welcome;

    document.body.appendChild(d);

}

HTML:

<label id=1 onclick=a(this)>aa</label>

<label id=2 onclick=a(this)>bb</label>

<label id=3 onclick=a(this)>aa</label>

actually what happens is when i click the any of three labels in html. another label is created and displays welcome. now when i click the newly created label welcome it does not display anything...... that is the onclick event added to newly created label is not working ....... any suggestion.................
