series.dataFields.valueY = "value";
series.dataFields.categoryX = "category";
series.id='101'
series.dataItem.setProperty("Id",101);

  alert("Clicked on " + ev.target.dataItem.categoryX + ": " + ev.target.dataItem.valueY+":"+ev.target.dataItem.dataContext.id);
});*

Clicked on Distribution: 1500:undefined

Not sure what you're trying to do here. What does the link which has Line Series have to do with Columns? Usually an object has a component property which is a reference to the series it belongs to. I would try ev.target.component or ev.target.dataItem.component to see if it's a reference to the columns' series. If it is, then you should be able to just find .id from it. — notacouch

try this
columnSeries.columns.template.events.on("hit", function(ev) { alert("Clicked on " + ev.target.dataItem.categoryX + ": " + ev.target.dataItem.valueY+":"+series.id); });
