Server side code to jQuery DatePicker

I need pass server side data from ColdFusion to jQuery DatePicker for a date time value from my backend database like following code.

<cffunction name="myFunction" access="remote" returnformat="json">

Since jQuery needs xml or JSON data type, I only need pass a piece of data, do I still need pass JSON data type including ROWS, TOTAL and all the information as well?

Regards,

Your help and information is great appreciated,

Iccsi,
