Some changes are required here.
1. modal-footer is included inside modal-body.
2. move modal-footer out and move the close and save buttons under it.
3. Remove classes(pull-right and form group) from buttons div as they are not required in modal-footer.
4. In the button with class close change it's style="color:black" as i have changed close css to color white in different page and thus close was not visible in the modal.
