cfform - Filter by calendar and radio buttons

I am stuck to go more than this... The "All" and calendar filter doesnt work...

<cfscript>
contactsQuery = createObject("component","contacts").getContactsShort();
departmentsQuery = createObject("component","contacts").getDepartments();
</cfscript>

<cfform name="myForm" format="flash" height="300" width="600" skin="haloSilver">
<cfformitem type="script">
  function applyFilter( term:String, grid:mx.controls.DataGrid, columns:Array ):Void {
 
   var filterTerm:String = term.toString().toLowerCase();
 
   if(filterTerm.length > 0) {
    if(_global.unfilteredData[grid.id] == undefined){
     if (_global.unfilteredData == undefined){
      _global.unfilteredData = {};
     }
     _global.unfilteredData[grid.id]  = grid.dataProvider.slice(0);
    }
   
    var filteredData:Array = [];
 
    for(var i = 0; i< _global.unfilteredData[grid.id].length; i++) {
     var item:Object =  _global.unfilteredData[grid.id];
     var added:Boolean = false;
    
     for(var j = 0; j< columns.length; j++){
       if(!added){
       var value:String = item[columns].toString().toLowerCase();
       if(value.indexOf(filterTerm) != -1) {
        filteredData.push(item);
        added = true;
       }
      }
      else {
       break;
      }
     }
    }
 
   grid.dataProvider = filteredData;
 
   }
   else {
    if(_global.unfilteredData[grid.id] != undefined) grid.dataProvider = _global.unfilteredData[grid.id];
   }
  }
