Why can't I add the clientId of my textBox to the markup here so that I can find it using jQuery?

Question

I'm just trying to pass the client identifier of one text element txtPersonId for a click event, so that I can go to this textBox control and pass its jQuery wrapper to the loadePerson () function.

This is how I decal it in the aspx label:

<asp:Button ID="btnSearch" runat="server" Text="ARA" OnClientClick="loadPerson(jQuery('#<%=txtPersonId.ClientID %>'))"/>

But when I draw it,

<%=txtPersonId.ClientID %>

the place keeper remains as it is, and it is not replaced by the display identifier of the management client.

Any idea why this is happening and how can I overcome it?
