How to insert form inputs as a metadata into FS.Collection while uploading an image?

I insert images into FS.Collection, based on this example by Ethaan - https://github.com/Ethaan/simple-uploadFS/. But I need to upload 2 input values and 2 select values connected with image. I thought inserting them as a metadata, would be the best solution, because it works for storing Meteor.userId(). How do I store also those values ? 

Template.profile.events({
  'change #exampleInput':function(){
    var file = $('#exampleInput').get(0).files[0] //Some jQuery to get the value.
        fsFile = new FS.File(file);

        fsFile.metadata = {
          coolText:"coolText",
          ownerId:Meteor.userId(),
          title:$(event.target).find('[name=bookTitle]').val(),
          format:$(event.target).find('[name=bookFormat]').val(),
          category:$(event.target).find('[name=bookCategory]').val(),
          description:$(event.target).find('[name=bookDescription]').val()
         } //FS.File support metadata.
    BookImage.insert(fsFile,function(err,result){
        if(!err){
           console.log(result) //you should get an id here since the full object take more less 10 sec to upload
         }
     })
  }
});
