First of all nltobr can be used in the server code and not inside of JavaScript callback method loadComplete will will be executed after filling the grid. Seconds the callback loadComplete will be called after the grid content will be placed in the grid. If you want make some modification of resultSet data you should do this before the grid with the data are created.

You wrote about wrapping of content, but the usage of nltobr and the text example which you posted shows that you have just new line character \n inside of the text. It it is

The demo uses the text which you posted and contains \n inside of the text. The results looks like you want

If you really need wrapping of the text then I recommend you to read the following answers: this one, this one and this one.

UPDATED: If you need make bold the first line of multiline content of some column you can insert <strong> in the text. If you don't use autoencode: true option of jqGrid then you can modify input data before creating jqGrid. For example the demo modifies content of note column:

var i, str, a;

for (i = 0; i < mydata.length; i++) {
    str = mydata[i].note;
    if (typeof str === "string") {
        a = str.split("\n");
        if (a.length > 1) {
            a[0] = "<strong>" + a[0] + "</strong>";
            mydata[i].note = a.join("\n");
        }
    }
}

Another demo demonstrate how to use custom formatter to do the same. You should use the approach if you use autoencode: true option of jqGrid. Th formatter of note column are defined in the demo as

formatter: function (value) {
    var a;
    if (value == null || value === "") {
        return " ";
    } else if (typeof value === "string") {
        a = value.split("\n");
        if (a.length > 1) {
            a[0] = "<strong>" + a[0] + "</strong>";
            return a.join("\n");
        } else {
            return $.jgrid.htmlEncode(value);
        }
    } else {
        return $.jgrid.htmlEncode(value);
    }
}
