Dynamic Table + Onclick Event Not Working?

I'm trying to create a dynamic table with onclick event like this but onclick event seems to do nothing:

var srcTable = this.iContext.getElementById("tbody");
var tmpRow = null;
var tmpCell = null;[code]...

I found a few examples like this: tmpRow.onclick = function() { alert(this.rowIndex);};

but I need use selected data, maybe call a defined function. I already tried lines bellow but nothing works, because doSomething is not function of tmpRow object.

tmpRow.onclick = function() { doSomething(this);}; or tmpRow.onclick = doSomething(this); or

tmpRow.onclick = "doSomething(this)";
