[jQuery] How to programmatically ad a div element and animate it

Hi,

Im new to Jquery and have been trying to dynamically create a new div
element with document.createElement.

I can successfully insert this element into the dom but I want to
animate it on creation. After inserting the element into the DOM i try
and access it using a JQuery selector but it does not seem to find it.

Example code.

function CreateNewElement()
{

var container = $("#contentContainer");
var myDiv = (document.createElement('div'))
myDiv.setAttribute("id", "div1");
myDiv.innerHtml = "test content";
container.appendChild(myDiv);

$("div1").toggle("slow");

}

Any help greatly appreciated.

Many Thanks
Ham
