Dismiss button is not appearing

Its asking me to add a dismiss button to the $modal, I dont know exactly how.

js/app.js 
//Create the Modal
var $modal = $("<div id='modal'></div>");

//Create a placeholder for text in the modal
var $placeHolder = $("<p id='placeHolder'></p>");
$modal.append($placeHolder);

//Create a button to dismiss modal and add it to modal
var $dismissButton = $("<button>Dismiss</button>");


//Hide modal when button is pressed
$dismissButton.click(function(){
  $modal.hide(300);
});

$("body").append($modal);

//A function to show a modal
function displayModal(message) {
  $placeHolder.text(message);
  $modal.show();
}

//Show an example modal
displayModal("Hello World!");
index.html 
<!DOCTYPE html>
<html>
<head>
    <link rel="stylesheet" href="css/style.css" type="text/css" media="screen" title="no title" charset="utf-8">
    <title>Modal Example</title>
</head>
<body>
    <h1>Modal Example Page</h1>

    <script src="//code.jquery.com/jquery-1.11.0.min.js" type="text/javascript" charset="utf-8"></script>
    <script src="js/app.js" type="text/javascript" charset="utf-8"></script>
</body>
</html>

Do you need to append the button to the placeholder?

Hi Christopher,

Notice how $placeHolder was append to $modal by using $modal.append($placeHolder)?

Let's borrow that and reuse it for appending $dismissButton to $placeHolder in the code below:

//Create a button to dismiss modal and add it to modal
var $dismissButton = $("<button>Dismiss</button>");
$placeHolder.append($dismissButton);
