Scope within a template - ember.js

Question

I use the following template to display a table of all users.
<script type="text/x-handlebars" data-template-name="users">
<table>
{{#each model itemController="user"}}
<tr>
<td>{{lastName}}</td>
<td>
{{#if isNew}}
<button {{action 'save' this}} class="btn btn-small">Save</button>
<button {{action 'discard' this}} class="btn btn-small">Discard</button>
{{else}}
{{#linkTo 'user.edit' this activeClass="disabled" classNames="btn btn-small"}}Edit{{/linkTo}}
{{/if}}
</td>
</tr>
{{/each}}
</table>
{{#unless newUserCreate}}
<p>
{{#linkTo 'users.new' classNames="btn btn-small"}}Create a new user{{/linkTo}}
</p>
{{/unless}}
</script>
Below the table I use a {{#unless newUserCreate}} which I'd like to use within the table too but because of a different scope I can't. How can I fix the following snippet to get it working? The User doesn't have a newUserCreate. Only the Users has.
{{#if isNew}}
{{#unless newUserCreate}}
<button {{action 'save' this}} class="btn btn-small">Save</button>
<button {{action 'discard' this}} class="btn btn-small">Discard</button>
{{/unless}}
{{else}}
{{#linkTo 'user.edit' this activeClass="disabled" classNames="btn btn-small"}}Edit{{/linkTo}}
{{/if}}
app.js
App.UsersRoute = Ember.Route.extend({
model: function() {
return App.User.find();
}
});
App.UsersNewRoute = Ember.Route.extend({
model: function() {
return App.User.createRecord();
},
renderTemplate: function() {
this.render({ into: 'users' });
},
activate: function() {
this.controllerFor('users').set('newUserCreate', true);
},
deactivate: function() {
this.controllerFor('users').set('newUserCreate', false);
}
});
