I have this code in my javascript section

```
function abc() {
    return (confirm("Are you sure you want to delete this from your list?"));
}

```

I have this code at my code behind

```
btn_CallAbc.Attributes["onclick"] = "return abc();"

```

But pop up message truncated when I click on the button as picture below.

Any idea how to solve it?
