how to us blur() function with input mask

how to us blur() function with input mask

I am using this input mask plugin,  http://digitalbush.com/wp-content/uploads/2013/01/jquery.maskedinput-1.3.1.min_.js. What I am trying to do is to use the blur(). Currently right now, I have blur working, but only to a certain extent. What I mean is that if the text field is empty, the blur() works. But if the text field contains data, the blur() is still kicking in and displaying the value that I have set for blur into the textfield rather than keeping what is inputting in the field. I am unsure of why this is happening. This is the coding that I am working with right now. 

  1. jQuery(function ($) {
  2. $.mask.definitions['~']='[+-]';
  3.                         $('.run').mask('99:99');
  4. $('.run').val('TBD');
  5. $('.penalty').mask('99:99');
  6. $('.penalty').val('TBD');
  7. //$('.com').val('TBD');
  8.             
  9.         })


  12. $(document).ready(function()
  13. {
  14. if ($(this).val() == "")
  15. {
  16. $('input[type="text"]').blur(function()
  17. {
  18. //$(this).unmask();
  19. $(this).val("TBD");
  20. });
  21. }
  22. });

I have it set up to only blur on text fields. With my mask, the input would be inputted like: 01:00. Thank you in advance for your help. I feel like this is a simple fix, but I can not seem to see where it is that i am not looking.
