I am having trouble applying a different array for a combobox

I have created a datagrid, and then I am trying to use cellrenderer to put a combobox in a column.

Normally I set up the datagrid, then use the following code to create the column that the combobox is going in:

var column = new DataGridColumn("species_id");
column.headerText = "species_id";
column.width = 70;
column.cellRenderer = "ComboBoxCell";
dgIndividualBirdData.addColumn(column);

A sample array I am wanting to add is [{label: "Test", data: 1}];

The class is as follows:

import mx.controls.ComboBox;
import mx.controls.DataGrid;

class ComboBoxCell extends MovieClip {

private var _ccbMenu:ComboBox;
private var listOwnerataGrid;
private var owner:MovieClip;
private var createClassObject:Function;
private var getCellIndex:Function;
private var getDataLabel:Function;

function ComboBoxCell() {
init();
}

private function init():Void {
createClassObject(ComboBox, "_ccbMenu", 1);
_ccbMenu.dataProvider = [];
_ccbMenu.addEventListener("change", this);
}


private function change(oEvent:Object):Void {
listOwner.editField(getCellIndex().itemIndex, getDataLabel(), _ccbMenu.value);
}

public function getPreferredWidth():Number {
return 100;
}

public function getPreferredHeight():Number {
return 25;
}

public function setSize(nWidth:Number, nHeight:Number):Void {
_ccbMenu.setSize(nWidth, _ccbMenu.height);
}

public function setValue(sLabel:String, oItem:Object, sState:String):Void {
_ccbMenu.visible = (oItem != undefined);
for(var i:Number = 0; i < _ccbMenu.length; i++) {
if(_ccbMenu.getItemAt(i).data == oItem[getDataLabel()]) {
_ccbMenu.selectedIndex = i;
break;
}
}
}

}

Just not exactly how to do this
