showHideChildren in chremo not working about bihisankey

I solve the problem.
This append because when you double click - two event are called : 'dblclick' and 'dragstart',
and 'dragstart' event overrides the 'dblclick' event.
To fix it I change the code from:

node.filter(function (d) {
    return d.children.length;
})
.on("dblclick", showHideChildren);

// allow nodes to be dragged to new positions
node.call(d3.behavior.drag()
 .origin(function (d) {
      return d;
 })
 .on("dragstart", function () {
      this.parentNode.appendChild(this);
 })
 .on("drag", dragmove));

to be:

node.filter(function (d) {
    return d.children.length;
})
 
// allow nodes to be dragged to new positions
var drag = d3.layout.force().drag()
 .on("drag", dragmove)

node.on("dblclick", showHideChildren)
 .call(drag);
