Refresh map and layers in ARCGIS javascript -


i have drop down in page, when drop down value changes contents of map i.e data loaded should change.it loads first time when again changed not changing. new arcgis map , want reload map. tried several methods doesn't help. below code please suggest way fix this.

  require([         "esri/map",         "esri/timeextent", "esri/dijit/timeslider",         "esri/geometry/point",         "esri/symbols/picturemarkersymbol", "esri/graphic",         "esri/layers/graphicslayer",         "esri/geometry/polyline",         "dojo/_base/array", "dojo/dom", "dojo/domready!"     ], function (             map, timeextent, timeslider,             point, picturemarkersymbol, graphic,             graphicslayer, polyline,             arrayutils, dom             ) {           var globallocationarray = //my json data latitude , longitude          var map;

also time extent needs refreshed. note: when dropdown changes call entire function above. please suggest way refresh contents loaded arcgis map. thank in advance

i have created angular spa webapi backend using adal js authentication.as there no roles in ad, need manually add role claims in order give users access different api controllers. the roles stored in database. expecting inject claim through call webapi after authentication ad. webapi code might this. identity.addclaim(new claim("role", "user")); var ticket = new authenticationticket(identity, props); var accesstoken = startup.oauthbeareroptions.accesstokenformat.protect(ticket); is possible replace adal idtoken new token? is viable solution or there other better way handle this? as initial token generated azuread, possible edit token add new claim? appreciated. graph api supporting group claims. see here: http://justazure.com/azure-active-directory-part-4-group-claims/ if @ examples on page, users assigned groups , app can check group in claims. in current version of portal, need app manifest , modify it.
