D3.JS : recover cell value when click in a row - d3.js

Question

I have made a table from a csv with d3.js. When I click in a cell I want to get the value of the last cell in its row .
I tried this :
var container = d3.select("body")
.append("table")
.attr("id","myTable");
//header
var headers=container.append("thead").append("tr")
.selectAll("th")
.data(titles)
.enter().append("th")
.text(function(d) {
return d;
});
var rows=container.append("tbody")
.selectAll("tr").data(dataCSV)
.enter().append("tr")
.on('click',function(d){
if(d3.select(this).classed("highlight")){
d3.selectAll("tr").classed("highlight", false);
}else{
d3.selectAll("tr").classed("highlight", false);
d3.select(this).classed("highlight", true);
}
});
rows.selectAll("td")
.data(function (d) {
return titles.map(function (k) {
return { 'value': d[k], 'name': k};
});
}).enter()
.append('td')
.attr("style","width:"+widthCellule+"%")
.attr('data-th', function (d) {
return d.name;
})
.text(function (d) {
return d.value;
})
/* Here is my mistake , I d'ont know */
.on('click',function(d,i,j){
column=i;
last_column=titles.length;
alert(d3.select('id','myTable').rows[j].cells[last_column].innerHTML);
});
