InPlace editing of ASP.NET Master Pages with jQuery

Hi I am trying to get the inPlace editing functionality. But this time its in Master page of an ASP.net application. I have a label control (for title of each web page) on master page. And in my content page I want to allow user to edit that title. Scenario is that Label should be converted to textbox when user click label. edit and then when textbox will loose focus, it should be converted to updated label. I don't want to change my master page contents. Otherwise may be I can add a hidden textbox on masterpage to replace it with label. But my concern is that Can I do this without editing my master page? I tried to work with JQuery .replaceWith() method. But I am new to JQuery and asp.net. Please help me thanks.

I tried stephen's solution but getting object not supported Javascript runtime error. JS Code is given as :

<script type="text/javascript" src="../Scripts/jquery-1.4.2.min.js" ></script> 
<script type="text/javascript" src="../Scripts/jquery-1.3.2.min.js" ></script> 
<script type="text/javascript" src="../Scripts/jquery/jeditable.js" charset="utf-8">      </script>
<script type="text/javascript">
     $(document).ready(function() {
        $(".click").editable("~/AdminArea/Setup/SetupFixedText.aspx", {
         tooltip: "Click to edit...",
         style: "inherit"
     });

     });

</script&开发者_StackOverflow社区gt;  

And in aspx I have a label first I assigned calss to label but now have placed label in "b"

div id = 'lblcontent' 
h3 class="BlueHeading"
b class="click" style="display: inline"
asp:Label  ID="lblContentTitle" runat =  "server"  EnableViewState="False"  
/asp:Label
/b

/h3
/div   

I removed angle brackets as this editor takign it as html.

EDIT Given Posted Code

Change your aspx page to this:

<div id='lblcontent'>  
 <h3 class="BlueHeading"> 
  <b style="display: inline"> 
   <asp:Label  ID="lblContentTitle" runat="server" CssClass="click" EnableViewState="False"></asp:Label> 
  </b>  
 </h3> 
</div>
