    Default ExtJS 4.0.7: Dynamic FieldSet with closable behavior

    Code:
        Ext.define('Ext.form.ClosableFieldSet', {        
            extend: 'Ext.form.FieldSet',
            alias: 'widget.closablefieldset',
            initLegend: function () {
                var me = this;
                me.callParent(arguments);
                if (!me.legend.closable) {
                    me.legend.insert(1, Ext.widget('tool', {
                        type: 'close',
    
                        handler: me.onCloseClick,
                        scope: me
                    }));
                    me.legend.closable = true;
                }
            },
            onCloseClick: function () {
                if (this.ownerCt) {
                    this.ownerCt.remove(this, true);
                }
            }
        });

    Moving to the Ext JS 4 Examples forum.

    You shouldn't use Ext.define within Ext.onReady.
