Is there a way to hook up a callback that fires whenever a cross-filter resizes filter?

Question

I have several diagrams built using dc.js. I can achieve the desired functionality by adding a callback to each diagram dc.js.on ("filterted", function (chart) {}), but this is annoying because I have to attach the same callback to every chart. And the error is prone, because when new diagrams are added, someone must remember to attach an event handler. I would rather just attach the callback to the base crossfilter. Is it possible?

Is there any way to optimize this ...

var ndx = crossfilter(data);
var dimAlpha = ndx.dimension(function(d) {return d.alpha});
var dimBeta = ndx.dimension(function(d) {return d.beta});
var groupAlpha = dimAlpha.group().reduceSum(function(d) {return 1;});
var groupBeta = dimBeta.group().reduceSum(function(d) {return 1;});

dc.pieChart(myDomId1)
  .dimension(dimAlpha)
  .group(groupAlpha)
  .on("filtered", function(chart) {
    //do stuff
  });

dc.pieChart(myDomId2)
  .dimension(dimBeta)
  .group(groupBeta)
  .on("filtered", function(chart) {
    //do stuff
  });

into something like that ...

var ndx = crossfilter(data);
var dimAlpha = ndx.dimension(function(d) {return d.alpha});
var dimBeta = ndx.dimension(function(d) {return d.beta});
var groupAlpha = dimAlpha.group().reduceSum(function(d) {return 1;});
var groupBeta = dimBeta.group().reduceSum(function(d) {return 1;});

dc.pieChart(myDomId1)
  .dimension(dimAlpha)
  .group(groupAlpha);

dc.pieChart(myDomId2)
  .dimension(dimBeta)
  .group(groupBeta);

ndx.on("filtered", function() {
  //do stuff
})

function my_func() {
    // do stuff
}

dc.pieChart(myDomId2)
    .dimension(dimBeta)
    .group(groupBeta)
    .on("filtered", my_func);

dc.chartRegistry.list().forEach(function(chart) {
    chart.on('filtered', function() {
        // your event listener code goes here.
    });
});

:

function my_func(chart,filter) {
// do stuff
}

 dc.pieChart(myDomId2)
.dimension(dimBeta)
.group(groupBeta)
.on("filtered", my_func);
