Touch provides additional bindings to handle touch events in knockout. All touch events heavylifting is done by hammer.
Below are some code examples on how you can use touch to handle some touch events:
<div id="touchme" data-bind="tap:tapHandler"></div>
Now everytime you tap the div tapHandler will be called. You can find a better demo inside SimpleDemo.html which is a part of touch. Actually it's just a converted example from hammer. But it will let you see the difference between using touch and not using touch.
More examples are on their way!
