Paging not working

Question

Hey guys,
     I am having major trouble getting paging to work with my datagrid.  Here is what is happing right now. 
After data is send to ColdFusion CFC, "count" function is called, and returns correct result, but then the "get" function is called over and over, and data is not even displayed in my datagrid.  Here is what my code looks like
<?xml version="1.0" encoding="utf-8"?>
<mx:Panel xmlns:fx="http://ns.adobe.com/mxml/2009"
    xmlns:s="library://ns.adobe.com/flex/spark"
    xmlns:mx="library://ns.adobe.com/flex/halo"
    xmlns:cfservice="services.*" width="100%" height="100%"
    paddingLeft="0" paddingRight="0"
    horizontalGap="0" verticalGap="0" layout="vertical"
    styleName="catalogPanel" title="Search Result"
    creationComplete="initSearchResultPanel()">
    <fx:Script>
         protected function initSearchResultPanel():void{
               util.app.addEventListener(SearchDBEvent.SEARCH_DB_EVENT,searchDBRequest);
          protected function searchDBRequest(event:SearchDBEvent):void{
                var obj:Object = event.struct;
                var d:DataManager=SearchRPC.getDataManager(SearchRPC.DATA_MANAGER_SEARCHDBRESPONSE);
                d.pageSize=obj.PAGESIZE;
                getSearchRSLTResult.token = SearchRPC.getSearchRSLT(obj);
                downloadBttn = new LinkButton();
                downloadBttn.label = "Download Search Sequences";
                downloadBttn.name = obj.ENVIRONMENT;
                downloadBttn.addEventListener(MouseEvent.CLICK,function (e:MouseEvent):void {
                    downloadSeqRequest(e,obj); });
                this.addChild(downloadBttn);
]]>
    </fx:Script>
    <fx:Declarations>
        <cfservice:SearchRPC id="SearchRPC" showBusyCursor="true" fault="util.faultHandler(event)"
            destination="ColdFusion" endpoint="http://localhost/flex2gateway" source="cfc.SearchRPC"/>
        <!--<s:CallResponder id="getSearchRSLTResult" result="searchDBHandler(event)"/>-->
        <s:CallResponder id="getSearchRSLTResult"/>
    </fx:Declarations>
    <mx:DataGrid id="searchDBResult" dataProvider="{getSearchRSLTResult.lastResult}"
        editable="false" width="100%" height="100%">
        <mx:columns>
            <mx:DataGridColumn headerText="sequenceId" dataField="sequenceId"/>
            <mx:DataGridColumn headerText="sequenceName" dataField="sequenceName"/>
            <mx:DataGridColumn headerText="sequenceLen" dataField="sequenceLen"/>
            <mx:DataGridColumn headerText="hspBitScore" dataField="hspBitScore"/>
            <mx:DataGridColumn headerText="blastDb" dataField="blastDb"/>
            <mx:DataGridColumn headerText="hitName" dataField="hitName"/>
            <mx:DataGridColumn headerText="hspAlignLen" dataField="hspAlignLen"/>
            <mx:DataGridColumn headerText="hspEvalue" dataField="hspEvalue"/>
            <mx:DataGridColumn headerText="hspSimilarity" dataField="hspSimilarity"/>
            <mx:DataGridColumn headerText="hspIdentity" dataField="hspIdentity"/>
        </mx:columns>
    </mx:DataGrid>
</mx:Panel>
I would ideally like to get my datagrid created in an action script instead of creating my datagrid as an mxml component.
Am I doing something wrong or missing something? Please help me figure this out
Thanks
Jay

No, I am not using my own paging scheme.  In Flash builder 4 I have setup my DataService for a ColdFusion cfc.  Then configure a return type, and enabled paging. In flex is am using rpc call as below to communicate with my cfc.
<fx:Declarations>
        <cfservice:SearchRPC id="SearchRPC" showBusyCursor="true" fault="util.faultHandler(event)"
            destination="ColdFusion" endpoint="http://localhost/flex2gateway" source="cfc.SearchRPC"/>
        <!--<s:CallResponder id="getSearchRSLTResult" result="searchDBHandler(event)"/>-->
        <s:CallResponder id="getSearchRSLTResult"/>
    </fx:Declarations>
