Boolean Scope Value of a Directive

Let's say I have a directive which looks like:

<foo-bar bar-foo="booleanValue"></foo-bar>

booleanValue here belongs to the parent scope - the scope of the controller which is attached to the view in which the above directive element is located.

Now, in my directive, I have defined the directive as follows:

app.directive('fooBar', function() {
    return {
        restrict: 'E',
        scope: {
            barFoo: '=barFoo'
        },
        link: function(scope, iElement, iAttrs) {
           scope.$watch('barFoo', function() {
               if(scope.barFoo !== true) return;
           });
           //Code to execute when barFoo is true
        }
    };
});

Problem here is that the value that is passed to barFoo is a boolean value, but it ends up being a string value. Thus `if (scope.barFoo !== true) will always be a success and the linker function never executes.

I do not want to change the code to if (scope.barFoo === "true").

How do I pass a boolean value into the scope?

EDIT : I wish to add here that booleanValue is indeed a boolean value (passed as true usually) by the parent controller into the directive. Just that when the value is passed, it gets converted to string instead of remaining boolean.

Assuming the value is set properly in the controller, it should be passed as boolean to the directive.

This plunker illustrates this.
