How to add FeatureLayer outside of initialization code

How would i add a FeatureLayer from outside the initializing function?

example:

require(
[
"esri/map",
"esri/layers/FeatureLayer",
"esri/dijit/PopupTemplate",
  "esri/geometry/Point",
  "esri/graphic",
  "dojo/domReady!"
],
function(Map, FeatureLayer, PopupTemplate, Point, Graphic)
{

map = new Map("mapDiv", { basemap: "streets", center: [22, 65], zoom: 5 });
getBasestationList();

});
});

function getBasestationList() {

fromdatetime = fromdatetime.toLocaleString();
todatetime = todatetime.toLocaleString();

  $.ajax(
  {
      type: "post",
      url: "{% url 'get_latest_basestation_list' %}",
      data:
      {
          "csrfmiddlewaretoken": "{{ csrf_token }}",
          "fromdate": fromdatetime,
          "todate": todatetime,
  },
  success: function (data, status)
  {
      featureLayer = new FeatureLayer(data, { id: 'basestations' });
      map.addLayers([featureLayer]);
  },
  error: function (request, status, error)
  {
      alert(request.responseText);
  }
});
};

However this gives me an error that FeatureLayer is not defined, if I do this in the intializing function it works, however I need to be able to add stuff to the map outside of the initializing function.

FeatureLayer, and other Esri modules, will only be in scope of the callback that is passed into require (which is what I think you mean by initialization function).

You can define other functions within that function and then set up listeners/events so that your functions will fire based on user actions.
