```
<md-checkbox ng-repeat="primaryPrograms in ctrl.primaryProgramStudies" ng-model="ctrl.primaryProgramStudiesSelected[primaryPrograms.id]">
  {{primaryPrograms.name}}
</md-checkbox>

```

Selected Checbox : 

```
{{ctrl.primaryProgramStudiesSelected | json}}

```

Output i am getting :

```none
Selected Checbox : 
[null,true,true,true,null,true,null,true,null,true,null,null,true] 

```

How can i get the List of Checked Values.
