Not working if ng-model is of datatype number

[DJHightower]

Successfully tested your component with model-values of type string.
But if i bind it to a model of type number the component always Shows 'Nothing selected'.
I tried it with static values like in this sample code:

            <ol class="nya-bs-select form-control" ng-model="testmodel">
                <li value="0" class="nya-bs-option">
                    <a>
                        Beratungswunsch durch Kunden
                    </a>
                </li>
                <li value="1" class="nya-bs-option">
                    <a>Beratung durch Beraterinitiative</a>
                </li>
            </ol>

in JavaScript:

this works: $scope["testmodel"] = "1";
this does not work: $scope["testmodel"] = 1;

Then i tried to help myself using dynamic options. I created this array in my viewmodel:

        $scope.GuidanceInitiatorOptions = [
            {
                Id: Model.GuidanceInitiator.Customer,
                DisplayName: "Beratungswunsch durch Kunden"
            },
            {
                Id: Model.GuidanceInitiator.Analyst,
                DisplayName: "Beratung durch Beraterinitiative"
            },
        ];

and modified my html to:

            <ol class="nya-bs-select form-control" ng-model="testmodel">
                <li class="nya-bs-option" nya-bs-option="option in GuidanceInitiatorOptions track by option.Id">
                    <a>{{option.DisplayName}}</a>
                </li>
            </ol>

But this always writes the full option-object into my ng-model "testmodel".But i only want to store the numeric value "Id"! I tried to change the select-statement to "option.Id as option in GuidanceInitiatorOptions". But that gives exceptions in your code.
Whats the correct way to bind to the Id in this case? Looks like there is no example for this in your collection.

You need to use value expression in each option, see the example of Value Expression
In your second example, you can add a attribute value="option.Id" to nya-b-option directive

<ol class="nya-bs-select form-control" ng-model="testmodel">
      <li class="nya-bs-option" value="option.Id" nya-bs-option="option in GuidanceInitiatorOptions track by option.Id">
           <a>{{option.DisplayName}}</a>
      </li>
</ol>

Can we add ng-change to nya-bs-select dropdown??
If yes,please share some example

[lordfriend]

ng-change relies on the native form controls, this directive is not a native form control
