javascript - angularjs select the first value in select box -

i need highlight first value 'fullname' in select box using angularjs. using angularstrap selectbox.

controller,

  $scope.accountinfo.owners = [      {         "accounts":null,       "phoneumber":null,       "email":null,       "fullname":"mita dasgupta",       "mobilephonenumber":null,       "noteflag":false,       "number":130000000484    } ] 

template,

<button type="button" class="btn btn-default" placeholder="pleasae select"    data-ng-model="owner.fullname"    data-html="1"    bs-options="owner owner.fullname owner in accountinfo.owners"     bs-select>     action <span class="caret"></span> </button> 

i tried way, value not selecting default.

you should have different ng-model name used owner in ng-options selectedowner

<button type="button" class="btn btn-default" placeholder="pleasae select"    data-ng-model="selectedowner"    data-html="1"    bs-options="owner owner.fullname owner in accountinfo.owners"     bs-select>     action <span class="caret"></span> </button> 

then need set value of ng-model controller.

$scope.selectedowner = $scope.accountinfo.owners[0];
