Question

I am trying to bind the click event to an element dynamically generated using the data with d3.js.

d3.select("#mylist").selectAll('li').data(data_arr).enter().append("li").html(
        function(d)
        {
            var element = document.createElement('div');
            element.innerHTML = '<div id="innerDiv"></div>';

            var divToClick = element.querySelector('#innerDiv');
            //Using jquery to get cross browser event binding
            $(divToClick).click(function(){
                alert('hello!');
            });



            return element.innerHTML;
       });

I know that the problem is that I am returning an string (innerHTML) but if I return the element it doesnt work. Any help?

(The real code is much more complex, I just copied here the important part).

Here is the answer.

 var li_arr = d3.select("#mylist").selectAll('li').data(data_arr).enter().append("li").html(
    function(d)
    {
        var element = document.createElement('div');
        element.innerHTML = '<div id="innerDiv"></div>';
        return element.innerHTML;
   });

 li_arr.select('#innerDiv').each(function(d,i)
       {
            var mydiv = d3.select(this);
            mydiv.on('click',function(){
                alert('hello');
            });
       });
