I am able to get the aggreate values from server to client, but could not display it on the template. Am i missing something here.Appreciate your help.

//client side javascript
Template.DashboardCategoriesChart.helpers({
'CategoryAggregateItem':function(){
var res;
Meteor.call("getAggregateCategoriesSum",function(errors,results){
console.log("results value: "+ JSON.stringify(results))
return results ;

}
});

//stringfy value returned
results value: [{"_id":"Household","totalAmount":420},{"_id":"Insurance","totalAmount":235},{"_id":"Family","totalAmount":1358},{"_id":"Utilities","totalAmount":5371.5},{"_id":"Automobile","totalAmount":500},{"_id":"Home Office","totalAmount":290},{"_id":"Travel","totalAmount":14},{"_id":"Food","totalAmount":303}]

//Template

            {{#each  CategoryAggregateItem}}
                <tr> 
                    <td>{{_id}}</td><td>{{totalAmount}}</td> 
                </tr>
