only change query option data not trigger http request

[fantaishao]

In my project , I put some additional parameters in the query options.
These query options can be changed by the user .

After uploading a file successfully, I only change the query options and keep the image file uploaded just now , and then I want to save it. But the http request is not triggered.

     $scope.flowInitOptions = {
         target: 'api/upload/pic',
         query: function(flowFile, flowChunk) {
           return $scope.initParams;
         },
         forceChunkSize: true,
         singleFile: true,
         testChunks: false,
         uploadMethod: 'POST',
         headers: getHeaders(),
         generateUniqueIdentifier: UUID.generate,
         permanentErrors: [400, 404, 415, 500, 501,401]
       };

    $scope.save = function($file, $event, $flow, type) {
         $flow.opts.query = angular.copy($scope.initParams);
         $flow.opts.query.publishDate = $scope.formatTime(angular.copy($scope.initParams.publishDate),'YYYY-MM-DD','');
         $flow.opts.query.scanEndDate = $scope.formatTime(angular.copy($scope.initParams.scanEndDate),'YYYY-MM-DD','');
         $flow.opts.query.scanStartDate = $scope.formatTime(angular.copy($scope.initParams.scanStartDate),'YYYY-MM-DD','');
         $flow.opts.query.articleClassifyId = angular.copy($scope.initParams.articleClassify.id);
         $flow.opts.query.classifyFlag = angular.copy($scope.initParams.classifyFlagTmp)?1:0;
         $flow.opts.query.scanType = angular.copy($scope.initParams.scanTypeTmp)?1:0;
         $flow.opts.query.useWebLib = angular.copy($scope.initParams.useWebLibTmp)?1:0;
         if(type == 'retry') {
           $flow.files[0].retry();
         }else {
           $flow.upload();
         }
       };

<div class="add-img-library add-work-library" ng-controller="AddImgLibraryController"
   flow-init="flowInitOptions"
   flow-file-added="!!{png:1,gif:1,jpg:1,jpeg:1}[$file.getExtension()];someHandlerMethod($file, $event, $flow)"
   flow-file-success="saveSuccess( $file, $message, $flow )"
   flow-complete="infoComplete( $file, $message, $flow )"
   flow-file-error="saveError( $file, $message, $flow )">
</div>

is there a cleaner way, I can trigger the http request right when I only change the query option,but don't change the text file or img file?
