How to retrieve a missing value

I'm not sure how to complete this challenge.

Take a look at the app.js and preview. The aim of this application is to show what the user types in to the input field and preview it in the H1 tag. Almost all the code is there, something is missing. Retrieve the value from the input. I forgot how to do it. Could you finish for me. Thanks.

js/app.js 
//Select the input for the title for blog post.
var $titleInput = $("#title");

//Select the preview h1 tag
var $previewTitle = $("#titlePreview");

// Every second update the preview
var previewTimer = setInterval(updatePreview, 1000);

function updatePreview(){  
  //Get the user's input
  var titleValue;
  //Set the user input as the preview title. 
  $previewTitle.text(titleValue.input);
}
index.html 
<!DOCTYPE html>
<html>
<head>
  <link rel="stylesheet" type="text/css" href="theme.css">
</head>
<body>
  <div id="form">
    <label for="title">Blog Post Title</label><input id="title" name="title" value="" placeholder="Enter your blog title here">
  </div>
  <div id="preview">
    <h1 id="titlePreview"></h1>
  </div>
  <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>
theme.css 
  #form {
    width: 45%;
    float: left;
  }
  #preview {
    width: 45%;
    float: right;
  }
  label {
    width: 20%;
    display: inline-block;
  }
  input {
    width: 70%;
  }

You need to set a value for the variable titleValue with the value from the input field.

sorry if i'm a gravedigger but i don't get the solution even with your help ^^'

i did this : var titleValue = $titleInput.val("input");

it tells me h1 says [object] [object] !

so it might be obvious but i don't see it haha
