innerHtml with ASP.NET and JQuery Mobile
===

I'm working on a mobile search, that uses your location to determine a zip code server side, but when trying to set two labels to the latitude and longitude to send to the server, I get an error claiming that the innerHtml is null. Upon further inspection, the element is null. Why could this be?

    <%@ Page Title="" Language="C#" MasterPageFile="~/Site1.Master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Search.Default" %>
    <asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
    </asp:Content>
    <asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
    <script language="javascript" type="text/javascript">
        navigator.geolocation.getCurrentPosition(foundLocation, noLocation);
        var latitude;
        var longitude;
        function foundLocation(position) {
            latitude = position.coords.latitude;
            longitude = position.coords.longitude;
            alert('Your location: ' + latitude + ', ' + longitude);
        }
        function noLocation() {
            //Do something here in the case that no location is found, or user denies access
        }
        function getLocation() {
            document.getElementById("ct100_ContentPlaceHolder1_lblLat").innnerHtml = latitude;
            document.getElementById("ct100_ContentPlaceHolder1_lblLong").knnerHtml = longitude;
        }
    </script>	
    <div data-role="page">
	    <div data-role="header">
		    <h1>Provider Search</h1>
	    </div>
	    <div data-role="content">
            <asp:Button ID="btnSearch" Text="Search" runat="server" data-role="button" OnClientClick="getLocation()" OnClick="btnSearch_Clicked"></asp:Button>
            <asp:Label ID="lblLat" runat="server"></asp:Label>
            <asp:Label ID="lblLong" runat="server"></asp:Label>
            <p></p>	
        
	    </div>
    
    </div>

    </asp:Content>

I'd like to note that everything in this document is working perfectly, except for the setting of the labels.

Also, the ID prefix ct100_ContentPlaceHolder1_ is generated by asp.net during runtime, and this can be confirmed by looking at the page source when I am debugging.

Any help?
