Simple confirm modal on inputs / links / whatever trough data-attr. Will launch a (Twitter) Bootstrap modal on elements that have a data-confirm-action="confirm". Some settings available. **Needs loads of improvements**

bootstrap-confirm.js

// Confirmation modal on elements that have 'confirm' class.
// Will launch a modal and ask for confirmation.
// data-confirm-action="confirm" - Will enable the confirm modal
// data-confirm-title="" - Custom title, optional
// data-confirm-text="" - Custom modal text, optional.
