HOW TO remoteSort multiple columns?

Hi:

I'm interested in sending more than 2 columns and directions to the server.

ie.

Code:

{
    "sortParams": [
        {
            "column": "one",
            "sort": "DESC"
        },
        {
            "column": "two",
            "sort": "ASC"
        },
        {
            "column": "three",
            "sort": "DESC"
        },
        {
            "column": "four",
            "sort": "ASC"
        }
    ]
}
