Ionic-toggle /ion-checkbox issue

ionic-toggle and ionic-checkbox both the element are not working implementation here

<li class="item item-toggle">
     Tip of the Day
     <label class="toggle toggle-balanced">
       <input type="checkbox" ng-change="tipOftheDay()" ng-model="usersettings.checked" ng-checked="usersettings.checked" >
       <div class="track">
         <div class="handle"></div>

on ng-change call back function am getting the true/false value and then storing those value in localstorage.So when I am going to next state and coming to this state the values true/false getting properly but the checkbox state is always showing true,if the settings was set to false also.
