jsf commandbutton confirm don't show any message

I have a <h:commandButton> on my page connected with action in my bean. It work just fine, but I wanted to add confirmation message. When I used:
<h:commandButton onclick="confirm('Are you sure?')">
it alco works just fine. But when I try to get string from bean, by making it looks like this: <h:commandButton onclick="confirm('#{bean.confirmQ}')">
it doesn't display this string. In getter for this string I invoke method to take some info from DB, and I format it then I return it. When I use this approach nothing is shown, not even empty box, and page looks like just refreshing.

Here is code from bean:

private String confirmQ;

public String getConfirmQ() {
    WycenioneAuta wa = getWycenioneAuto();
    String question = "are you sure \n" + wa.getName + "?";
    confirmQ = question;
    return confirmQ;
}

public void setConfirmQ(String confirmQ) {
    this.confirmQ = confirmQ;
}
Solution

    1. Escape the line by writing String question = "are you sure \\n" + wa.getName + "?";

    2. If your String variable is confirmQ , then the right EL pointing to that variable is #{bean.confirmQ} and not #{bean.confirm} as you've written.
