Hey Community,

Im working on an App and you should be able to push Data in an Array.
I console logged the array, the inputs and everything works fine, except of that this isnt showing up in the ng-repeat.
Here is my code, maybe you can help me.

index.html

<script id="templates/addEx.html" type="text/ng-template">
  <ion-view view-title="GymHelper">
    <ion-content padding="true" ng-controller="OverallCtrl">
      <div class="list">
        <label class="item item-input item-floating-label">
          <span class="input-label">Exercise Title</span>
          <input ng-model="exer.title" type="text" placeholder="Title">
        </label>
        <label class="item item-input item-floating-label">
          <span class="input-label">Exercise Sets</span>
          <input ng-model="exer.set" type="text" placeholder="Sets">
        </label>
        <label class="item item-input item-floating-label">
          <span class="input-label">Exercise Reps</span>
          <input ng-model="exer.rep" type="text" placeholder="Reps">
        </label>
        <label class="item item-input item-floating-label">
          <span class="input-label">Extra Information</span>
          <input ng-model"exer.inf" type="text" placeholder="Extra Information">
        </label>
        <label class="item item-input item-select">
        <div class="input-label">
          Muscle
        </div>
        <select ng-model="selOption">
          <option>Chest</option>
          <option>Biceps</option>
          <option>Back</option>
          <option>Stomach</option>
          <option>Legs</option>
          <option>Triceps</option>
          <option>Shoulders</option>
          <option>Traps</option>
        </select>
      </label>
      </div>
      <button class="button button-block button-positive" ng-click="createEx(exer)">
        Create Exercise
      </button>

    </ion-content>
  </ion-view>
</script>

<script id="templates/chest.html" type="text/ng-template">
  <ion-view view-title="GymHelper">
    <ion-content ng-controller="OverallCtrl">
        <ion-checkbox ng-repeat="chest in chestEx">
          <b class="exTitle">{{chest.title}}</b>

          <h3 class="exInf">{{chest.exInf}}</h3>
        </ion-checkbox>
    </ion-content>
  </ion-view>
</script>

app.js

app.controller('OverallCtrl', function($scope, $ionicListDelegate, $state) {

  $scope.chestEx = [

          {title: "Crowls", sets: 3, reps: 15, exInf: "Make 5 minute pause between Sets."},

                  ]

  $scope.selOption == "Chest";

  $scope.createEx = function(exer) {
    console.log(exer.title);
    console.log($scope.chestEx);
    if($scope.selOption == "Chest"){
      $scope.chestEx.push({title: exer.title, sets: exer.set, reps: exer.rep, exInf: exer.inf});
      console.log("Pushed to Chest Array.");
      $state.go('chest')
    };
  }
