Clearing data from UIForm

You can use simple jQuery on Cancel button click to clear the form

$("#btnCancel").click(function(){
   $("#form")[0].reset();
});

Or you can add a new button with type reset or change Cancel button type to reset if you are not doing any other operation with Cancel button

<button type="reset" value="Cancel">Cancel</button>

Thank you for the response. I am performing other operations with the cancel button though, hiding the form and resetting a list of items.

Then use first approach using jQuery. If you already have click event attached to your cancel button then add form reset code at the end of the click function
