None of the answers are working - Error AST node to a simple object: CallExpression

I have tried it with several different syntaxes and I am getting following error - AST node to a simple object: CallExpression

index.html 
<!DOCTYPE html>
<html lang="en">
<head>
    <title>Document</title>
    <link rel="stylesheet" href="style.css">
</head>
<body>
    <h2>My Favorite Things</h2>

    <ul class="favorite-things">
        <li>Kittens</li>
        <li>Rainbows</li>
        <li>Unicorns</li>
        <li>Sprinkles</li>

Hi there! The thing you're trying to prepend should be a simple string and not another jQuery object. You will need to remove the dollar sign and a pair of parentheses from the argument passed to prepend.

 $(this).prepend('<input type="checkbox"/>');

Hope this helps! :sparkles:

In my case was able to pass the challenge, so thanks. But when I previewed the change I didn't see any difference, so why do I have to leave out the Jquery method? In the videos before we've used it without any problems?!
