 To ensure your AngularJS application works on IE please consider:

 2. For the `type` attribute of buttons, use `ng-attr-type` tags instead of
    `type="{{ someExpression }}"`. If using the latter, Internet Explorer overwrites the expression
    with `type="submit"` before AngularJS has a chance to interpolate it.
