Help: Calling TextBox Changed Event using Jquery

Help: Calling TextBox Changed Event using Jquery

Hi All,
         I am a novice and I have issue in firing an server side event from Jquery. Scenario: I have a textbox in user control which has a event TextChanged that I need to fire when the text box loses the focus, I am trying to do in blur event. See the below code, 

Jquery code: 
$(document).ready(function () {
$('#NumericTextbox').blur(function () {

});

C# Server side code: 

protected void NumericTextbox_TextChanged(object sender, EventArgs e)
{
OnNumericValueChange();
}

How do I call the event in jquery? Please let me know if you require any other detials. Help

Note: Eventhough I set the Autopostback property to true on Textbox, the event does not fire appropriately, that is the reason I have gone for Jquery whenever it loses focus.
