You may need to elaborate your question, it's a little difficult to understand the exact workflow that you're trying to achieve.

 

For example, are you asking to fornat a text field to display only numerical characters (no letters or special characters)?

 

And Are you also asking if you can add a button object to the PDF so that when a user clicks  on it it will delete the numeric strings entered in that field  in the same way like a backspace key would do when it is pressed repeatedly on an actual keyboard peripheral device?
