Controller SlideMenu on Sencha - extjs

Question

Help me :(
I've been researching on how to reference methods of a button using MVC on Sencha Touch, but none of the articles has worked fine for me since I declare all my controls on the constructor of my views.
View :
extend: 'Ext.Container',
xtype: 'main',
requires: [
'Ext.Menu',
'Ext.Img',
'Ext.Toolbar',
'Ext.Container'
],
config: {
scrollable: true,
type: 'card',
fullscreen : true,
html: [
'<img max width="100%" height="auto" src="resources/image/Head.png" />',
'<h1>STMIK Akakom Yogyakarta</h1>',
'<h1><img max width="40%" height="auto" src="resources/image/Logo.png"/> </h1>'
],
items: [
{
xtype: 'toolbar',
docked: 'top',
title: 'Selamat Datang',
items: [
{
xtype: 'button',
iconCls: 'list',
ui: 'plain',
action : 'slideMenu'
}
]
},
{
xtype: 'toolbar',
docked:'bottom'
}
],
},
Controller :
config: {
views: [
'Main',
'MenuNav',
'HalamanUtama'
],
refs: {
main: {
selector:'main',
xtype:'main',
autoCreate: true
},
menunav:{
selector:'menunav',
xtype: 'menunav',
autoCreate: true
},
halamanutama: {
selector: 'halamanutama',
xtype: 'halamanutama',
autoCreate: true
}
},
controll: {
'button[ui=plain]':{
tap: 'slideMenu'
},
'button=action[MenuNavOption]': {
tap: 'handleNavigation'
}
}
},
initialize: function(){
var menuNav = this.getNav();
Ext.Viewport.setMenu(menuNav,{
side: 'left',
reveal: true
});
},
slideMenu: function(){
if(Ext.Viewport.getMenus().left.isHidden())
{
Ext.Viewport.showMenu('left');
}
else
{
Ext.Viewport.hideMenu('left');
}
},
handleNavigation: function(button){
switch(button.getText()){
case 'HalamanUtama' :
var halamanutamaView = Ext.Viewport.child('halamanutama');
if (!halamanutamaView) {
halamanutamaView = this.getHalamanutama();
Ext.Viewport.add(halamanutamaView);
}
Ext.Viewport.setActiveItem(halamanutamaView);
break;
default :
var mainView = Ext.Viewport.child('main');
if(!mainView){
mainView = this.getMain();
Ext.Viewport.add(mainView);
}
Ext.Viewport.setActiveItem(mainView);
}
this.hideNav();
}
}
but still my slide menu did not show up :( please can you show me the way. Any help would be appreciated. Thank you.
