Open new ajax function if button is in previous ajax condition?

Question

JavaScript

Good time of the day.
Tell me how to open a new ajax function if the button is in the condition of the previous ajax?
Here is the code

success: function(xml) {
  if ($(xml).find('domain').text() == ''){
  }
  else
  {
  $('#result').append('<input class="button" type="submit" onclick="getRrRecords();" name="getRrRecords" value="Получить">');
  }
  }
  });
  }
  });//Конец первого ajaxPostXML
function getRrRecords() {
  alert('test');
}

I tried to open it through the class, onclick, the button just stupidly reloads the page, the alert does not come out
Help me figure out what I'm doing wrong?
