Can I get a testcase? This works for me:

var cnt = Ext.Viewport.add({
    xtype : 'container',
    items : [
        {
            xtype : 'fieldset',
            title : 'Action',
            items : [
                {
                    xtype   : 'button',
                    text    : 'Remove',
                    ui      : 'decline',
                    handler : function() {
                        cnt.destroy();
                    }
                }
            ]
        }
    ]
});
