How i fix first row data constant based on a condition and sort rest of data in datagrid according to date?

I want to fix first row data in datagrid according to a coloumn Status, if data status is new then it should be on index 0 first row, and sort other datagrid rows based on the date coloumn. i already sorted all data on the base of a single coloum like date. i also tried to sort with the given function but it's not working fine.

public static function sortDataGridMultiColumn(columnOne: String, columnTwo: String, decending: Boolean, array: ArrayCollection): void {

   var sortThese: Sort = new Sort();
   sortThese.fields = [new SortField(columnOne, false, decending),
   new SortField(columnTwo, false, decending)];
   array.sort = sortThese;
   array.refresh();

}

first i sort data in data grid through this function

public static function sortDataGrid(columnId:String , decending:Boolean , array:ArrayCollection):void
        {

            var sortThese:Sort = new Sort();            
            sortThese.fields = [new SortField(columnId, false, decending)];
            array.sort = sortThese;             
            array.refresh();    
        }

then i Use this function for manually setting the required data on the first index.

 public static function sortingNWFDataGrid(arrayCol:ArrayCollection):void 
            {
                var currentIndx:Number = 0;
                for(var i:int = 0 ; i < arrayCol.length; i++){
                    if(arrayCol.getItemAt(i).statusId == UserStatusConstants.NEW_STATUS_ID){
                        currentIndx = i;
                        break;
                    }
                }
                var newObj:Object = new Object();
                newObj = arrayCol.getItemAt(currentIndx) as Object;
                arrayCol.removeItemAt(currentIndx);
                arrayCol.refresh();
                arrayCol.addItemAt(newObj, 0);
                arrayCol.refresh();
            }

any one with better solution or with different approach please provide here.
