Angularjs change checkbox value according to server response

I have two groups of checkboxes where users choose their options and save it to the database as a string (is there a better option?).

Is it possible the get this string response back from the server and set each value back to the corresponding checkbox to keep it checked?

<form class="list">

    <ion-toggle toggle-class="toggle-balanced" ng-model="data.turnOnOff" ng-true-value="'On'" ng-false-value="'Off'" ng-change="data.showConfirm(data.turnOnOff)">Databases</ion-toggle>
    <div class="spacer" style="height: 10px;"></div>

    <ion-list ng-show="bd">
        <ion-checkbox ng-repeat="(key, value) in db" ng-model=value.checked ng-change="checka()"></ion-checkbox>
    </ion-list>
    <div class="spacer" style="height: 10px;"></div>


    <ion-toggle toggle-class="toggle-balanced" ng-model="data.escritorio" ng-true-value="'On'" ng-false-value="'Off'" ng-change="data.openEscritorio(data.escritorio)">Office</ion-toggle>
    <div class="spacer" style="height: 10px;"></div>

    <ion-list ng-show="officee">
        <ion-checkbox ng-repeat="(key, value) in office" ng-model=value.checked></ion-checkbox>
    </ion-list>
    <div class="spacer" style="height: 10px;"></div>
</form>
<div class="spacer" style="height: 10px;"></div>
<button style="color:#FFFFFF;" class="button button-balanced button-block" ng-click="insert()">Ok</button>
