Corner & CFC ColdFusion

I am trying to pick up AngularJS with the back end of ColdFusion and stumbled upon a few roadblocks. I am changing my Make app http://angularjs.org/ with the CF art gallery database. I am trying to link ColdFusion CFF with an Angular app using AJAX.

Below is my artist.cfc:

<cfcomponent>

<cffunction name="getArtists" access="remote" >
    <cfargument name="firstName" default="">
    <cfargument name="lastName" default="">

    <cfquery name="getArtists_sql" datasource="cfartgallery">
        SELECT
            firstname as text,
            lastname as done 
        FROM artists
        WHERE 0=0
    <cfif firstName neq "">
        AND ucase(firstname) like ucase('%#FIRSTNAME#%')
    </cfif>
    <cfif lastName neq "">
        OR ucase(lastname) like ucase('%#LASTNAME#%')       
    </cfif>
    </cfquery>

    <cfreturn getArtists_sql>
</cffunction>

</cfcomponent>

I invoke CFC using AngularJS with the following code:

function TodoCtrl($scope, $http) {
    $http.get('cfc/artists.cfc?method=getArtists&returnformat=json').
        success(function (response) {
            $scope.todos = data.DATA;
    }).
        error(function (data) {
            $scope.todos = data;
        });
}

I know that I am getting an answer. The following is the JSON string for Chrome developers:

{
"COLUMNS":
    ["TEXT","DONE"],
"DATA":[
    ["Aiden","Donolan"],
    ["Austin","Weber"],
    ["Elicia","Kim"],
    ["Jeff","Baclawski"],
    ["Lori","Johnson"],
    ["Maxwell","Wilson"],
    ["Paul","Trani"],
    ["Raquel","Young"],
    ["Viata","Trenton"],
    ["Diane","Demo"],
    ["Anthony","Kunovic"],
    ["Ellery","Buntel"],
    ["Emma","Buntel"],
    ["Taylor Webb","Frazier"],
    ["Mike","Nimer"]
]}

This is not like the Angular notation used in their demo:

[
{text:'learn angular', done:true},
{text:'build an angular app', done:false}
]
