Elements retaining original values ​​in jQuery objects after PostBack

I use ASP.NET 3.5 in combination with the brutal UpdatePanel , jQuery.delegate()and JavaScript object literals.

I use jQuery.delegate()to save event handlers that fire after PostBack , as expected.

The problem is with jQuery objects stored in the object properties of the object on init(), where they store the values ​​that they had before ASP.NET PostBack .. p>

Here is my javascript :


Sfaic

SFAIC = 
{
    masterPages: { cs: "CS_", cp: "CP_" },
    contentPages: { cs: "CSContent_", cp: "CPContent_" },

    isSecurePage  : false,

    $body         : undefined,
    $container    : undefined,
    $updatePanel  : undefined,

    $textBox      : undefined,
    $errorLabel   : undefined
};


SFAIC.init ()

SFAIC.init = function () 
{ 
    log( "--> SFAIC.init() fired" );

    var self = this; 

    self.$body        = $( "body" );
    self.$container   = self.$body.find( "#container" );
    self.$updatePanel = self.getCSMasterElement( "UpdatePanel1", self.$container );
    self.$textBox     = self.getContentElement( "TextBox1" );
    self.$errorLabel  = self.getContentElement( "ErrorLabel1" );

    self.$updatePanel.delegate( self.$textBox.selector, "blur", function () 
    { 
       self.validateRequired( self.$textBox, self.$errorLabel ); 
    });

    self.$textBox.focus();
};


SFAIC.validateRequired ()

SFAIC.validateRequired = function ( $element, $errorLabel ) 
{
    if ( $element.val().length === 0 ) { $errorLabel.text( "Required" ); }
    else { $errorLabel.text( "" ); }
};


, SFAIC.init() , self.textBox jQuery. , . , .val() , . , , , , jQuery ?

        var namespace = SFAIC;
