/*
 * Buttons.js
 *
 * Use bootstrap loading state after submitting a form.
 *
 * Some form inputs are validaded before the submission
 * so triggering loading state on click events is not a
 * good idea. If the validation fails the errors will
 * be displayed but the button would be in loading state.
 *
 * We used to trigger it based on form submission but
 * we have a few forms that contain multiple buttons.
 * So now we mark the buttons as clicked on click and
 * put the clicked button into loading state on submit.
