jQuery Grid Plugin - jqGrid

Hi

I have a simple jqGrid which shows the data from one method. The data of the table is in 2 languages so I need to pass 5th parameter to my method with the current language to get only the attributes in this lanage.

I used the geeting started example from the demonstration page but my Object is a Coldfusion Component. But I think that doesnt change anything.

In the js config file I have this url defined

url:'/includes/components/WerkstoffDB.cfc?method=getData

The json string is this one:

            jsonReader: {
                root: "ROWS",
                   page: "PAGE",
                   total: "TOTAL",
                   records:"RECORDS",
                accountdata:"ACCOUNTDATA",
                cell: "",
                id: "0"
                }

How can I pass a 5th parameter (en or de) to my Method getData?

Here the head of my object:

    <cffunction name="getData" access="remote" returnformat="json">
        <cfargument name="page" required="no" default="1" hint="Page WerkstoffDB is on">
        <cfargument name="rows" required="no" default="10" hint="Number of Rows to display per page">
        <cfargument name="sidx" required="no" default="" hint="Sort Column">
        <cfargument name="sord" required="no" default="ASC" hint="Sort Order">

Here I want a 5th parameter
