How to change the current value of a select list bound with ng-options?

Question

I have a select list created like this:

    <div class="actionList" ng-repeat="selectedAction in outputDevice.selectedActions">
      <select class="outputAction" ng-model="selectedAction.value" ng-options="action as action.name for action in outputDevice.userDevice.baseDevice.outputs">
        <option value="">
          Select Action
        </option>
      </select>
    </div>

It is contained within a create/edit page. When the page is in edit mode, I want to chose which item in the list is selected, based on some values retrieved from the server. Currently the select list will populate with the correct options, but I can't make the select list start on the correct value. Here is the code where I populate the values on the page:

             for(var i =1; i<result.length; i++){
                var appyDevice = result[i];
                var userDevice = appyDevice.device;
                var selectedActions;

                if(appyDevice.outputs){
                    selectedActions = appyDevice.outputs;
                    for(var j =0; j<selectedActions.length; j++){
                        selectedActions[j].value = {
                            name: selectedActions[j].name,
                            id: selectedActions[j].id
                        };
                    }
                    $ctrlScope.outputDevices.push({
                        userDevice: userDevice, 
                        selectedActions: selectedActions
                    });
                }
            }
            $ctrlScope.$apply();

I set selectedActions[j].value, which the select list is bound to, however it does not update. Any ideas why this isn't working? Or other ways to do this?

EDIT: Here is a sample of the results JSON (ignore the redundant information and stuff, we're working on the serialization still):

Edit 2: As per the possible duplicate linked in the comments, I attempted to add an ng-init to no avail:

<select class="inputAction" ng-model="selectedAction.value" ng-options="action as action.name for action in inputDevice.userDevice.baseDevice.inputs" ng-init="selectedAction.value=selectedAction.name">

I think this is irrelevant anyways, as I am effectively doing this initialization in the following lines of my code:

                        selectedActions[j].value = {
                            name: selectedActions[j].name,
                            id: selectedActions[j].id
                        };

I've modified mb21's fiddle to get your code working and demonstrate initializing the values.

The issue is, when you use ng-model on the select and ng-options for the options, you must set the ng-model variable to the exact reference of the object that is being used to generate that option:

    for(var j =0; j<selectedActions.length; j++){
        selectedActions[j].value = userDevice.baseDevice.outputs[0];  // change index to select different initial value
    }
