Sencha Touch Making a simple button work

Question

I have a hard time debugging and understanding why the most basic stuff is going wrong in my sencha project. I use webstorm, but it can't seem to help me much with missspelling code. Most errors i get are unclear like undefined is not a function. Can anyone help me by showing me what I do wrong in the following code. I just want a button that does a console log.

View:

    Ext.define('imp.view.Test', {
        extend: 'Ext.form.Panel',
        alias: "widget.test",
        xtype: 'test',
        controllers: 'imp.controller.Test',
        requires: [ 'imp.controller.Test'],

        config: {
            title:'Test',
            scrollable: null,
            items: [

                {
                    xtype: 'button',
                    itemId: 'postButton',
                    ui: 'action',
                    padding: '10px',
                    text: 'Post'
                }]


        }

});

Controller:

Ext.define('imp.controller.Test', {
    extend: 'Ext.app.Controller',
    config: {
        refs: {
            testView: 'test'
        },
        control: {
            'test #postButton': {
                tap: 'onPostCommand'
            }
        }
    },

        onPostCommand: function (){
            console.log('klik');


        }

    }
);

What is a good way to debug and to learn Sencha Touch better, could anyone give me some advice? What books,sites etc. are good?

Update: This is the console log output and when i press the butotn just nothing happens.....

The best way to find out if there is something wrong with your code is using Firebug in Firefox or Developer Tools in Chrome.

Referring to your problem, I just removed the util.Utility from the code and it works fine. So you want to make sure if there is any Utility.js in the app/util folder. Also, Utility.js should follow Sencha class structure:

Ext.define('.util.Utility', { /*upper case "U" in important*/
      config : {
      }
});

At the end, you should see either the klik or an error in the console output.
