Question

I’m having an issue with binding an input from inside a view. I thought it would bind to the controller scope, but it seems to be binding to a child scope, so it’s not updating above.

Other items will bind like I expect if they’re inside an ng-repeat (I’m not sure why).

Here’s an example:

What’s the best way to bind the input to the correct scope if it’s not inside an ng-repeat?

Answer 1

In your example you will have better luck binding your $scope.test to an object instead of a primitive type like this:

$scope.test = { val: "test value" };

You can see this fiddle for a working example.

The child scope that gets created in the ngView will copy your value and since your original $scope.test is a primitive string it has no link to the parent value so your input will be modifying the child scope copy. When binding to an object your child scope has a copy of the object reference but will ultimately modify the same instance of the object.

You can take a look at this question for more information on creating a service to persist data across multiple controllers (which is a little similar to your question).

You can also look into using $parent as described in this answer though as Mark mentions it’s undocumented and might get messy if another child scope ever gets introduced somewhere.
