If you see no error, which I am guessing is the case, it means your request is failing. Since you have no error function, when your request fails, your jQuery code will do nothing.

Add something like this to your $.ajax object argument:

error: function(jqXHR, textStatus, errorThrown) {
  // now you can set a breakpoint or log textstatus/errorThrown
},
