d3.js - How can I use drag behavior and dblclick event with d3? -

-

i have been trying many hours , couldn't working. have element d3 draggable using drag behavior, , want add dblclick event, performs action when double clicked. couldn't dblclick event reached. have studied many ways of trying stop propagation within drag, , changing order of declaration of events, no success far. code like:

switch = box.append('rect')     .data([{x: point.x, y: point.y}])     .attr('transform', function (d) { return 'translate(' + d.x + ',' + d.y + ')'; })     .attr('height', 8)     .attr('width', 8)     .attr('stroke', color)     .attr('fill', color)     .on('dblclick', function () {       d3.event.stoppropagation();       alert('hello');  // doesn't enter     }, true).call(d3.behavior.drag().on('dragstart', function () {       d3.event.sourceevent.stoppropagation();     }).on('drag', function (d) {       d.x += d3.event.dx;       d.y += d3.event.dy;       d3.select(this).attr('transform', 'translate(' + d.x + ',' + d.y + ')');     }).on('dragend', function (d) {     }));

note "true" after on('dblclick', ..., true) declaration. trying prevent propagation.

any appreciated.
