Based on http://semantic-ui.com/behaviors/api.html#/usage, I think my code actually run.

Here is the code :

$('#new-modul').form({
  fields: {
    division: {
      identifier: 'division',
      rules: [
        {
          type   : 'empty',
          prompt : 'Please select division'
        }
      ]
    },
    application: {
      identifier: 'application',
      rules: [
        {
          type   : 'empty',
          prompt : 'Please select application'
        }
      ]
    },
    title: {
      identifier: 'title',
      rules: [
        {
          type   : 'empty',
          prompt : 'Please enter a title'
        }
      ]
    },
    description: {
      identifier: 'description',
      rules: [
        {
          type   : 'empty',
          prompt : 'Please enter description'
        }
      ]
    }
  }
})
.api({
  url: './ajax/Ticket/new.php',
  method: 'POST',
  serializeForm: true,
  onComplete: function() {
    completeCreateNewModuleAction();
  }
});

But maybe something went wrong, so the error appears on my console.

Error :

API: jquery-serialize-object is required to add form data to an existing data object

And I don't know why. Anybody knows about this?

You need to include https://github.com/macek/jquery-serialize-object as stated in docs
