angularjs - Angular: How to prevent controller reload on state change -

-

i have settings view , settings subview:

     $stateprovider         .state('sidemenu.settings', {                 url: '/settings',                 views: {                     'maincontent': {                         templateurl: 'partials/settings/settings.html',                         controller: 'settingscontroller'                     }                 }             })             .state('sidemenu.default-location',{                 url: '/default-location',                 views:{                     'maincontent':{                         templateurl: 'partials/settings/defaultlocation.html',                         controller:'settingscontroller'                     }                 }             })

you can notice both use same controller: settingscontroller.

when call main settings view $state.go('sidemenu.default-location'); reloads settingscontroller again. why?

(i don't want use ng-show/hide)

my question if stay in controller , next state uses same controller how prevent controller reload?
