I copied your code and ran into the same issue. Then I looked at it closer and noticed you are missing a closing bracket in your isUrgencyTypeValid() function. The closing bracket for your for loop is missing. Firefox Error Console will also show this.

Once I added the bracket the alert worked fine.

function isUrgencyTypeValid()
{
    alert("asd");
    var i=0;
    for(i=0;i<$("radio[name='urgencyType']").length;i++)
        {
        if($("radio[name='urgencyType']")[i].checked)
        {
            alert($("radio[name='urgencyType']")[i].value);                 
            return true;
        }  
    } //this was missing
    return false;
}
