How to load data to a combo box or rad combo box in a Asp Repeater control using jquery

I want to reload data to a combo box (I’m using a rad combo box) in a asp.net repeater control which is in An update panel using jquery or javascript. I’m getting the required data from a web method and converting it to an object array like [id:1, name:john]. The attribute for id is ‘DataValueField’ and text is ‘DataTextField’. Is there a way I can do this in jquery ?
