Answer 1

Change ng-change="changeDraw(draw)" to ng-change="changeDraw(currentDrawResults)

var app = angular.module('app', []);

app.controller('fCtrl', function($scope) {



  $scope.lot = {
    lastDraws: [{
        drawDate: "2011-10-28T09:30:24.673Z"
      }, {
        drawDate: "2012-09-28T09:30:24.673Z"
      }, {
        drawDate: "2014-05-28T09:30:24.673Z"
      },




    ]
  };

  $scope.changeDraw = function(draw) {
    alert(draw.drawDate)
  }

});

  <div ng-controller="fCtrl">


    <select class="form-control" ng-model="currentDrawResults" ng-options="(draw.drawDate | date:'MMM d, y' ) for draw in lot.lastDraws track by draw.drawDate" ng-change="changeDraw(currentDrawResults)">
