 | auto          | Boolean   | By default, changes in the model will not automatically update the collection. However if set to true, changes in the client will be automatically propagated back to the collection. A deep watch is created when this is set to true, which sill degrade performance.  | No        | false     |
+| publisher     | Boolean/String   | By default, bindOne method will not automatically subscribe to the collection. However if set to true, bind will call Meteor.subscribe on the current collection. you can also set publisher to a string and then bind will call Meteor publish with that string.           | No        | false     |
