knockout js change input type when focused with a bindingHandler

Vote count:

I have logic that changes the "type" attribute of an input when that element becomes focused:

my.inputType = ko.observable('text');
my.passwordIsFocused = ko.observable();

my.passwordIsFocused.subscribe(function (isFocused) {
    if (isFocused) {
        my.inputType('password');
    }
});

<input id="password" type="text" data-bind="hasfocus: passwordIsFocused, attr:{ type: inputType}" />

I would like to use a custom binding handler to do this so I can apply it to different input fields.
