fix #14, data binding not working

[liujoey]

by passing a function to the changeWatcher, it make sure when scope.treeData had been changed, the arraySource inside changeWatcher should get a new copy.

I dont understand why you wrap it with jquery element. This is the tree instance of the js tree and it is working fine

[liujoey]

in my setup it doesn't work, the scope.tree is just a jqlite DOM element from the document (a div). I'm using angular 1.3.10, jstree 3.0.9, and jQuery 2.1.3. I don't know if something has been changed. Let me try to create the plunker.

-- update --
Yes you are correct, the problem I have is I load the jQuery library in a wrong sequence, it should be load before angular.js. Please feel free the move the 3b35033 commit

The commit 16a5de7 kind of make sense, because if you replace the treeData model, instead of just pushing to it, the reference is lost and no updates are made.

@SuricateCan I am not sure if it a good option to make it work when you replace the reference
