Uncaught TypeError: Object [object Object] has no method 'dataTable'

Hey,
I've been trying to use datatables in an ASP.NET page but it just doesn't seem to work. My table is the following:

<table id="searchMembers">
        <thead>
            <tr>
                <th>First Name</th>
                <th>Suname</th>
                <th>Email address</th>
                <th>Phone Number</th>
            </tr>
            
        </thead>
        <tbody>
            @foreach (var member in Model)
            {
                <tr>
                    <td>@member.FirstName</td>
                    <td>@member.SurName</td>
                    <td>@member.Email</td>
                    <td>@member.PhoneNumber</td>
                </tr>
            }
        </tbody>
        <tfoot>
            
        </tfoot>
    </table>

And my javascript section looks like this:

<script type="text/javascript" src="~/Scripts/jquery-1.8.3.js"></script> 
<script type="text/javascript">
    $(document).ready(function () {
        $('#searchMembers').dataTable();
    });
</script>

When I load the page I get the following error:

Uncaught TypeError: Object [object Object] has no method 'dataTable' SearchMembers:1283
(anonymous function) SearchMembers:1283
fire jquery-1.8.3.js:974
self.fireWith jquery-1.8.3.js:1084
jQuery.extend.ready jquery-1.8.3.js:406
DOMContentLoaded

After some searching I updated my jquery-ui to the latest (1.9.2) but it didn't help.

What am I doing wrong? I would so love to use datatables but I just can't get it working! Is it possible that I haven't copied some of the files or didn't copy them to the right place?

Thanks a lot in advance!
