Ionic app stops working

I am reading a json file and displaying in the view.
My JSON FILE
[
{
"DayNum": "1",
"Date": "January 01, 2015",
"Title": "Miracle Rain",
"By": "By Poh Fang Chia",
"Passage": "1 Kings 18:1,41-45",
"Memory": "I am God, and there is no other.Isaiah 46:9",
"Devotion": "Life is hard for the villagers..."
}
]
MY SERVICE
.factory('DevotionService',function($rootScope,$http){
var serviceUrl = 'file:///android_asset/www/';
var Devotion;
return {
getDevotion : function(dayNum){
return $http.get(serviceUrl + 'json/'+dayNum+'.json').then(function(data){
Devotion = data;
return Devotion;
});
}
}
})
My Controller
.controller('ViewDevotionCtrl', function($scope,$localstorage,$location,$ionicHistory,$cordovaDevice,DevotionService,$stateParams){

if($stateParams.dayId==0){
  Date.prototype.isLeapYear = function() {
    var year = this.getFullYear();
    if((year & 3) != 0) return false;
    return ((year % 100) != 0 || (year % 400) == 0);
  };

  // Get Day of Year
  Date.prototype.getDOY = function() {
    var dayCount = [0, 31, 59, 90, 120, 151, 181, 212, 243, 273, 304, 334];
    var mn = this.getMonth();
    var dn = this.getDate();
    var dayOfYear = dayCount[mn] + dn;
    if(mn > 1 && this.isLeapYear()) dayOfYear++;
    return dayOfYear;
  };
  var today = new Date();
  var daynum = today.getDOY();
  console.log(daynum);
  Devotion = DevotionService.getDevotion(daynum);
  **$scope.devotions = Devotion;** - this line causes the app to stop working

}else{
  Devotion = DevotionService.getDevotion($stateParams.dayId);
  console.log(Devotion[daynum].Title);
}

})
MY TEMPLATE

<ion-view title="View Devotion">
  <ion-header-bar class="bar-positive"><h1 class="title">View Devotion</h1></ion-header-bar>
  <ion-content>
    <ul ng-repeat="dev in devotions">
      <li>{{dev.Title}}</li>
    </ul>
  </ion-content>
</ion-view>
