I solved it by using 'hiddeName' for components inside the form. Through Ext.query() we can get all the hbox forms and from that form.getValues() will provide the values of components inside the form.

   forms = Ext.query(#formId); 
   for (var i=0; i < forms.length; i ++) {
     formValues = new Ext.form.BasicForm(forms[i]).getValues();
   }
