Typescript enum switch going to default instead of proper case

Issue

I have the following enum:

enum EditMode {
    View = 0,
    Edit = 1,
    Delete = 2
}

Let's assume I have a variable of the enum type

var editMode = EditMode.Edit;

Why does the following code not work (goes straight to default)?

switch (editMode) {
    case EditMode.Delete:
        // ...
        break;
    case EditMode.Edit:
        // ...
        break;
    default:
        // ...
        break;
}

Solution

I have found why this happens: somewhere in the code there is a activation function (I am using durandal) which passes this enum as a string (the function has the parameter marked as a enum but still it is a string). This is why my switch statement fails.

I simply converted the value to a number and now everything works as expected.
