Using Controller to Attach Events (sencha touch / extjs)

My experience in web programming is limited to intermediate, self-taught JS and jQuery with a dash of PHP. ExtJS is turning out to be an entirely different animal.

I can't figure out why my controller isn't doing what I expect, especially since I'm following the syntax that is used in the documentation (which is becoming increasingly useless as they fail to describe what is actually happening in the examples... but I digress).

Main.js

    Ext.define("cs.view.Main", {
         extend: 'Ext.TabPanel',
         tabBarPosition: 'bottom',
 
         requires: [
             'cs.view.form',
             'cs.view.location',
             'Ext.TitleBar',
             'cs.controller.geolocate'
             ],
 
         config: {
             tabBar: {
                 docked: 'bottom',
             },
             defaults: {
                 flex: 1
             },
             items: [
                 { xtype: 'form' },
                 { xtype: 'location' }
                 ]
             },
     });
 

form.js

Ext.define('cs.view.form', {
     extend: 'Ext.form.Panel',
     requires: 'cs.controller.geolocate',
     xtype: 'form',
     alias: 'widget.getLoc',
 
     config: {
         title: 'Home',
         iconCls: 'home',
         items: [
         {
             xtype: 'toolbar',
             docked: 'top',
             title: 'Client Finder'
         },
         {
             xtype: 'textfield',
             name: 'address',
             label: 'address'
         },
         {   
             xtype: 'textfield',
             name: 'dist',
             label: 'distance(mi)'
         },
         {
             xtype: 'button',
             ui: 'confirm',
             text: 'submit',
             id: 'submitButton',
             alias: 'widget.submitButton',
         }
             ]
         },
 });
 

geolocate.js

Ext.define('cs.controller.geolocate', {
     extend: 'Ext.app.Controller',
 
     config: {
         views: ['Main', 'form', 'location'],
         control: {
             aButton: {
                 tap: 'message'
             }
         },//control
         refs: {
             aButton: '#submitButton'
         },//refs
     },//config
 
     message: function(){
         Ext.Msg.alert("Success", "Finally!");
     }
 });
