"render": function(data, type, row) {
var html = data.amount + data.interes;
return html;
}
This image is not correct because when I display It will become 1005, 10040. The correct addition is 105 and 140 this is want to display.

@Teemu i don't know why display like this 1005, the correct is 105 I've used javascript operator `+` example `data1 + data2` like this. – Makuri David Apr 15 '21 at 10:03

Yes, but what values `data1` and `data2` have? – Teemu Apr 15 '21 at 10:04

@Teemu `data1 = 100 + data2 = 5' but the result is 1005, the correct result is `105`, what wrong of my code ? – Makuri David Apr 15 '21 at 10:07

1Seems you are just concatenating two string values, try converting them to number `parseInt(data.amount) + parseInt(data.interes)`. – Ravikumar Apr 15 '21 at 10:07
