Updating a jquery value -- HOW TO?

[pdinsd]

I have a gauge rendered on my form using the raphael jquery library.  The gauge renders correctly using the following code (placed inside a script property of a div element):

Code:

$('.PEERSON').kumaGauge({
   value : 20,
   showNeedle : false,
   valueLabel : {display : true,
                         fontColor : '#000',
                         fontSize : 20},
   title : {
       // show or hide this label
       display : true,
       // String the value of the title
       value : 'PEERS ON',
       // The font family of this label
       fontFamily : 'Arial',
       // The font color of this label
       fontColor : '#000',
       // Integer of The font size of this label (without px)
       fontSize : 20,
       // The font weight of this label
       fontWeight : 'normal'
    }
});

How can I change the "value" from Intraweb so that the gauge updates?  I know it's probably simple, but I can't see an easy way to update a jquery element's value from Delphi/Intraweb.

Any help would be greatly appreciated.
