}
else {

after close window i want to submit form automatically by using me.submitData() function

Answer 1

Add a listener to MySample.view.register like:
Ext.create('MySample.view.register', {
id: myId,
closeAction : 'destroy',
listeners: {
// catch the close action
'destroy' : function() {
me.submitData();
}
}).show();
The event to catch is based on which kind of component MySample.view.register is extending of.
