JQuery Uncaught Reference message

I have this function written:

<script type="text/javascript">
   function getStartDate(value) {
    $.post("gSearch.php", {dateSearch:value}, function(data){
        $('#results').html(data);
    )};
   }                            
</script>

and this piece of HTML:

<input id="startdate" name="startdate" type="text" onkeyup="getStartDate(this.value)">

but I get this in my console in Chrome; can any one help me as to why?

<script type="text/javascript">
   function getStartDate(value) {
    $.post("gSearch.php", {dateSearch:value}, function(data){
        $('#results').html(data);
    });
   }                            
</script>

The brace was not closed properly, or was that a typo ?
