------------------------------------

             Summary: z.angularBind should remove the existing AngularObject
                 Key: ZEPPELIN-2356
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-2356
             Project: Zeppelin
          Issue Type: Bug
    Affects Versions: 0.7.1
            Reporter: Jeff Zhang
            Assignee: Jeff Zhang


There're 2 issues in the current angular object usage in ZeppelinContext.

* z.angularBind would set a new value if the angularObject is existed, otherwise the registered watched will be called which might not be user expect
* z.angularWatch would register multiple watcher if the angularObject is existed, this also might not what user expect.

The above 2 issues means that either user have to run the paragraph only once, or they have to call angularUnbind before calling angularBind.

I have a suggestion that we could remove the existing AngularObject and create a new one in z.angularBind, and create new method angularSet for setting new value for AngularObject. [~moon] [~jongyoul]
