javascript - How to Pass data from Third-Party Library Callback (firebase) to View in AngularJS

Question

I'm working on upload files using angularjs and firebase I'm trying pass parameters from controller to view inside state_changed event It's not working , I can print it on controller but can't use it into view

these code that I used

// File or Blob named mountains.jpg
var file = "";

// Create the file metadata
var metadata = {
  contentType: 'image/jpeg'
};

// Upload file and metadata to the object 'images/mountains.jpg'
var uploadTask = storageRef.child('images/' + file.name).put(file, metadata);

// Listen for state changes, errors, and completion of the upload.
uploadTask.on(firebase.storage.TaskEvent.STATE_CHANGED, // or 'state_changed'
  function(snapshot) {
    // Get task progress, including the number of bytes uploaded and the total number of bytes to be uploaded
    var progress = (snapshot.bytesTransferred / snapshot.totalBytes) * 100;
    console.log('Upload is ' + progress + '% done');
    $scope.progress = progress;
    switch (snapshot.state) {
      case firebase.storage.TaskState.PAUSED: // or 'paused'
        console.log('Upload is paused');
        break;
      case firebase.storage.TaskState.RUNNING: // or 'running'
        console.log('Upload is running');
        break;
    }
  }, function(error) {
  switch (error.code) {
    case 'storage/unauthorized':
      // User doesn't have permission to access the object
      break;

    case 'storage/canceled':
      // User canceled the upload
      break;

    ...

    case 'storage/unknown':
      // Unknown error occurred, inspect error.serverResponse
      break;
  }
}, function() {
  // Upload completed successfully, now we can get the download URL
  var downloadURL = uploadTask.snapshot.downloadURL;
});
