Durandal child router updating bindings only once -

the router have created builds navigation model, it's missing update bindings need updated each time page loaded within childrouter (app.pagetitle, app.pagedescription).

is there way how map these updates durandal's lifecycle, activate event?

define([ 'durandal/app', 'plugins/router', 'knockout', 'app' ], function(app, router, ko, app) {      console.log("content start");      var childrouter = router.createchildrouter().makerelative({         moduleid : 'app/content/pages',         fromparent : true     }).map([ {         route : [ '', 'grid' ],         moduleid : 'grid/index'     }, {         route : 'details/:id',         moduleid : 'details/index'     }, {         route : 'details/tabs/base',         moduleid : 'details/tabs/base'     } ]).buildnavigationmodel();      console.log("cms title start");     app.pagetitle(app.i18n('app:modules.content.title'));     app.pagedescription(app.i18n('app:modules.content.subtitle'));     console.log("cms title stop");      return {         router : childrouter     }; }); 

the simplest solution works adding activate function , returning it. durandal call everytime page childrouter navigation model requested.

define([ 'durandal/app', 'plugins/router', 'knockout', 'app' ], function(app, router, ko, app) {      console.log("content start");      var childrouter = router.createchildrouter().makerelative({         moduleid : 'app/content/pages',         fromparent : true     }).map([ {         route : [ '', 'grid' ],         moduleid : 'grid/index'     }, {         route : 'details/:id',         moduleid : 'details/index'     }, {         route : 'details/tabs/base',         moduleid : 'details/tabs/base'     } ]).buildnavigationmodel();      function activate() {         console.log("cms title start");         app.pagetitle(app.i18n('app:modules.content.title'));         app.pagedescription(app.i18n('app:modules.content.subtitle'));         console.log("cms title stop");     }              return {         activate : activate,         router : childrouter     }; });
