Events not being triggered when re-setting value to last focused value

If you enter a value in a masked input field, then take away focus, and then regain focus again, setting the value to what it was when focus was regained will not trigger onchange or onkeypress events

Steps to reproduce:
See http://jsfiddle.net/k2s0hvcm/ for fiddle with input field.

Enter value 12 in the input box. You should see events triggered for changing the value to 1 and then changing it to 12.
Click outside the field, to take away focus.
Go back into the field. Delete the last character so 1 is the value in the input box. This event will be triggered as well.
Without taking away focus re-enter 2 so that 12 is the value. You will see no events were triggered for the new value of 12.

Looking through the code, I see that oldValue is used for both triggering the changed event on blur (https://github.com/igorescobar/jQuery-Mask-Plugin/blob/v1.14.0/src/jquery.mask.js#L113) as well as the on events (https://github.com/igorescobar/jQuery-Mask-Plugin/blob/v1.14.0/src/jquery.mask.js#L310) that are triggered from the behaviour method. It seems like these may want to be two different old values, one when focus was taken for triggering the change - and another based upon the last key press to trigger the onChange / onKeyPress methods.

@danbehar thanks for looking into the code... what is your use case exactly... any ideas on how to make it better?

In my specific instance, I had been binding to the onChange event to get the value after every change. There were instances where it did not end up getting the actual value that was in the input field. As I didn't need intermediate values, my workaround was to stop using this onChange event. If the intermediate values were needed, this workaround wouldn't work.
One way to make it better would be to not use oldValue inside of callbacks, which was set when the field received focus, but instead some new additional variable that would be set based upon the last value.
