ng-model into ui-gmap-marker - angularjs

Question

I need help to use ng-model directive with ui-gmap-marker. My example app.js is:
// DevicesController
$scope.devices = {
id: 1,
center: { latitude: X, longitude Y },
options: {
show: true,
name: 'device 1',
radius: 100
}
(...)
}
My index.html is:
<ul ng-controller="DevicesController">
<li ng-repeat="d in devices">
<input type="checkbox" ng-model="d.options.show">
<span>{{ d.options.name }}</span>
</li>
</ul>
(...)
<div id="map_canvas" ng-controller="DevicesController">
<ui-gmap-marker
ng-repeat="d in devicesMarkers track by d.id"
idkey="d.id"
coords="d.center"
ng-model="d.options.show">
</ui-gmap-marker>
(...)
How can I use ng-model? Doesn't work because I'm using the same controller e two different places? I want that the user be able to click in input checkbox and the marker appear/disappear.

Answer 1

I'd suggest simply wrap both the div in same controller rather than providing a separate controller to them.
Markup
<div ng-controller="DevicesController">
<ul>
<li ng-repeat="d in devices">
<input type="checkbox" ng-model="d.options.show">
<span>{{ d.options.name }}</span>
</li>
</ul>
(...)
<div id="map_canvas">
<ui-gmap-marker
ng-repeat="d in devicesMarkers track by d.id"
idkey="d.id"
coords="d.center"
ng-model="d.options.show">
</ui-gmap-marker>
</div>
(...)
</div>
Else maintain the data in share able service that will provide the data to both controller and will make sure, data should be updated in both places.
