AJAX :: Button Click Event Is Not Firing Inside The Accordion Pane?

Button click event from inside the accordion pane is not firing. Accordion pane contains tab container inside one of its panes (5th pane) to read data from user and to save that data into database. I have used a button to save data when user click on that button. For this button i have written a click event in code behind.

this is my click event

<asp:Button
ID="Save"
runat="server"
Text="Save"
OnClick="Save_Click"/>

and code behind code

protected
void Save_Click(Object sender,
EventArgs e)
{
//my code

}
for this page AutoEventWireup="true"
