$(document).ready(function(){
  $("#aButton").touch(function(origElement, origEvent){
    console.log('Original target ID: ' + $(origEvent.target).attr('id'));
  });
});

$.fn.touch = function (callback) {
    var touch = false;
    $(this).on("click", function(e){
        if (!touch)
        {
            console.log("I click!");
            let callbackReal = callback.bind(this);
            callbackReal(this, e);
        }else{
            touch = true;
        }
        touch = false;
    });
    $(this).on("touchstart", function(e){
        if (typeof e.touches != typeof undefined)
        {
            e.preventDefault();
            touch = true;
            console.log("I touch!");
            let callbackReal = callback.bind(this);
            callbackReal(this, e);
        }
    });
}
