AngularJS, Select2 - binding true/false values in dropdown with ngDisabled

Question

I am trying to do the following:

• Show a simple Yes/No dropdown (with values true and false as IDs) using Select2
• Bind the value of the dropdown to a model using ngModel
• Enable/Disable a textbox using the true/false value

Here is a plunker

I have a regular example with a checkbox which works, and a select2 example.

The difference is that I am binding the select2 dropdown with an array of values. And the JSON seems to reflect a datatype of string associated with the true/false values, i.e. they are bound as strings "true" and "false".

EDIT: I realize that tag values can only be strings. Thus, see my answer.

Answer 1

Works with:

data-ng-disabled="YesNoSelValue=='false'"

Answer 2

 <select name="" class="form-control" id="selectId" ng-model="disableTextBox">
                    <option></option>
                    <option value="true">True</option>
                    <option value="false">False</option>
                </select>
                <input ng-disabled="disableTextBox == 'true'" type="text" />

JS: $scope.disableTextBox = "true";
