Swipe event on webView

We have a webview where the scrolling worked fine.

But when we add this code:

web_content.addEventListener('swipe', function(e) {
        var swipe_town_name;
        swipe_town_name = central.nextSwipeTown(name, e.direction);
        // alert("swipe_town_name:" + swipe_town_name);
        Ti.App.fireEvent('openTown', {
            townName : swipe_town_name
        });
    });

Any work around for this, as we need to swipe in new content into the webView, and have scrolling of the content?
