ng-click(parameters) open a popup window with dropdown,then selected item and parameters sent to the service

I'm new to Angular-js. I'm using JSP for front end and passing values from UI to controller.Now I need to open a new popup list where user can select an option, then pass all parameters to service ..

ng-click="rewardRetry(singleWinner)"

controller --->

$scope.retryRewardDTO = {
  "mobile_number" : null,
  "draw_id" : 0,
  "lottery_ticket_id" : 0,
  "prize" : 0,
  "reward_method" :null
};

(mobile_number,draw_id,lottery_ticket_id,prize) I can assign like this

$scope.rewardRetry = rewardRetry;
function rewardRetry(rewardRetryDTO) {                     
  $scope.retryRewardDTO.draw_id=rewardRetryDTO.draw_id;
  $scope.retryRewardDTO.lottery_ticket_id=rewardRetryDTO.lottery_ticket_id;
  $scope.retryRewardDTO.prize=rewardRetryDTO.prize;
  $scope.retryRewardDTO.mobile_number=rewardRetryDTO.mobile_number;
  //$scope.retryRewardDTO.reward_method=rewardRetryDTO.reward_method;
}

But here retryRewardDTO.reward_method -->user should be select in popup option. (wallet,m_cash,reload,,, ....etc)

calling to service

winnerService.winnerService.rewardRetry(
  $scope.retryRewardDTO,
  function(data, headers) {
    winnerSearch();
  }, function() {
});

I'm trying do something like below link.but couldn't get a proper output.please some helps to me...
