Coldfusion2016 cfgrid rowdblclick listener not firing

Following this example Easy Rich Internet Applications With ColdFusion 8 — SitePoint  the rowdblclick event does nothing. Same result for the example code and my  augmented code. Neither work. Is there a different way of adding a listener in CF2016?

<script type="text/javascript">

function initGrid(){ 

  var grid = ColdFusion.Grid.getGridObject("aaaGrid");

  grid.on("rowdblclick", showAAAForm);

  }

function showAAAForm(){

    var aaaId = ColdFusion.getElementValue("aaaGrid", "gridForm", "id");

    var url = "aaaForm.cfm?aaaId="+aaaId; 

    ColdFusion.navigate(url, "aaaWin");     

    ColdFusion.Window.show("aaaWin"); 

  }

function submitForm() {  

clearErrors();  

ColdFusion.Ajax.submitForm("aaaForm", "AAA_submit.cfm", submitCallback, errorHandler);  

    }

function submitCallback(response){  

      var errors = ColdFusion.JSON.decode(response);  

      var valid = true;  

      for(i in errors){  

    document.getElementById(i+"Error").innerHTML = errors;  

    valid = false;  

      }  

if(valid){  

ColdFusion.Window.hide("aaaWin");  

ColdFusion.Grid.refresh("aaaGrid", true);  

}  

  }

function newAAA(){  

var url = "aaaForm.cfm" ;  

ColdFusion.navigate(url, "aaaWin");      

ColdFusion.Window.show("aaaWin");  

}

function errorHandler(code, msg)

    {

        alert("Error!!! " + code + ": " + msg);

    }

    function clearErrors(){

    document.getElementById("fNameError").innerHTML = "";

    document.getElementById("lNameError").innerHTML = "";

    }

</script>
