hi guys im having trouble in implement both pinch zoom by hammer.js and image map, after i put in the pinch zoom the image is able to zoom in and drag but unable to click on the area map which i have been written earlier. Any solution to this?

         <script src="hammer.showtouches.js" type="text/javascript"></script>

    <div class="content">
            <div id="pinchzoom">
            <img src="images/map.jpg" width="529" height="300" id="rect" alt="Zoo" usemap="#zoomap">
            <map name="zoomap">
            <area shape="circle" coords="200,200,50" href="javascript:openPopup3" alt="NYTimes" >
            </map>
         </div>

Code:
var hammertime = Hammer(document.getElementById('pinchzoom'), {
        transform_always_block: true,
        transform_min_scale: 1,
        drag_block_horizontal: false,
        drag_block_vertical: false,
        drag_min_distance: 0
    });

var rect = document.getElementById('rect');



var posX=0, posY=0,
    scale=1, last_scale,
    last_posX=0, last_posY=0,
    max_pos_x=0, max_pos_y=0;

hammertime.on('touch drag transform dragend', function(ev) {
    switch(ev.type) {
        case 'touch':
            last_scale = scale;
            break;

        case 'drag':
            if(scale != 1){
                    posX = saved_posX + ev.gesture.deltaX;
                    posY = saved_posY + ev.gesture.deltaY;
                    if(posX > max_pos_x){
                        posX = max_pos_x;
