You could try creating your own custom binding handler to achieve this:

ko.bindingHandlers.initializeValue = {
    init: function(element, valueAccessor) {
        valueAccessor()(element.getAttribute('value'));
    },
    update: function(element, valueAccessor) {
        var value = valueAccessor();
        element.setAttribute('value', ko.utils.unwrapObservable(value))
    }
};
