how to add onclick event to create new element in javascript

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.................

For creating an attribute to a HTML tag, sometimes we have to add this:

yourTag.src
yourTag.src = 'http://lolxd.com/404.png'

But there are special attributes, and them have diferents ways for editing:

yourTag.classList
yourTag.className

And there is the onclick attribute, wichwe can use it like this:

// The first way
obj.onclick = function () { alert('lalala') }
// With the Event Listener
obj.addEventListener('click', function () { alert('lalala') }, false)
// Or, a text-render way
obj.setAttribute('onclick', 'alert(`lalala`)')

I recomend you the Event Listener way, but try all :D

You need to set d.onclick=function(){a(1);};, note that the case matters here (not "onClick").

[Edit]

Based on your comments and updated questions I've created a jsFiddle to demonstrate how you might turn your code into something that works.
