backbone stickit - reverting model changes

Question

I'm now testing backbone stickit for two-way data binding. Is there a way to revert the changes, for example, while editing a model data through a form, the user press the cancel button, as in the pic below

It seems the model was changed on the fly as we type in the form. What I want is when the user press the cancel button, the model will revert to its original value.

I read about updateModel which need a true value to confirm the model update. However how can my edit-view [cancel-event] trigger a false value to the updateModel function, so that the model will not be updated with the textfield value.

Do I need something like a global variable?

//global variable
var updateModelTitle = true;

//backbone stickit bindings
  bindings: {
    '#title': {
      observe: 'title',
      updateModel: 'confirmUpdate'
    }
  },
  confirmUpdate: function(val, event, options) {
    return updateModelTitle;
  }

//cancel button event click event
updateModelTitle = false;

Thanks in advance for any help.
