Answer 1

Assuming that "typeId" is your form field, you only have changed the name of the underlying dom element, but you also need to set the name for the ExtJS component:

typeId.name = 'newName';

Check out this example: https://fiddle.sencha.com/#view/editor&fiddle/1ngu

1. Open the "Network" tab in dev tools
2. Do a form submit by accessing "Form Submit"
3. Access "Change field name"
4. Do a form submit again and observe that the submitted name has changed
