data binding not working for me

[liujoey]

in the directive, when it first been initialized, it gets the data from outside model.

scope: {
                treeData: '=ngModel',
                shouldApply : '&'
            },

For instance I have assigned home.treeData to the directive, so scope.treeData also has the same data. Now if I change the value of home.treeData, it seem the scope.treeData was not updating, what am I doing wrong?

Hi,
check the demo code. If you still have questions, create a plunker and I will look on it
