Single jQuery POST with multiple buttons and responsive actions

I am sending the same POST value multiple times. Is it possible to just set the POST value once and then use it multiple times with different buttons?

Example: Complete code:

  $('#btn1').click(function(){   
        $.post("my.php",
            {
              status:$('input[name=radio]:checked').val(),
              name:$( '#name' ).val(),
              subject:$( '#subject' ).val()
            },
          function(response) {
            //do something with response...
          });
  });

I want to do something like this:

function getPost(){
   $.post("my.php",
   {
     status:$('input[name=radio]:checked').val(),
     name:$( '#name' ).val(),
     subject:$( '#subject' ).val()
     },
}

      $('#btn1').click(function(){   
            getPost();
              function(response) {
                //do AAAAA...
              });
      });

      $('#btn2').click(function(){   
            getPost();
              function(response) {
                //do BBBBB...
              });
      });
