Button click not detected
===

I have a Window, and it contains some textfields and a button. Here's the definition of the button;
              alias.widget:'mywin',
              ....

                {
                    xtype: 'button',
                    height: 40,
                    width: 110,
                    text: 'send',
                    x: 58,
                    y: 12,
                    action: 'buttonclick'
                },

In my controller, i am going to detect this button click and display a console.log statement. 

here's the code ;


init: function(application) {
        this.control({

            'mywin button[action=buttonclick]': {
                click: this.butClick
            }
        });
    },


    butClick: function(button,record) {
        console.log('Button clicked');


This is not getting displayed, and how can i solve it ?
