Check if AssignedTo has role

[heathers_]

On a field condition, if the assigned_to does not have a specific role, we'd like to clear the assigned_to value. If the assigned_to does have the role, we don't want to clear the value. This is being done through a scoped app. I've taken some suggestions from a few other posts and so far unable to achieve the goal. Currently, the value is clearing regardless of role.

Script Include

HrRoleUtils = Class.create();
HrRoleUtils.prototype = Object.extendsObject(global.AbstractAjaxProcessor, {

    hasRole: function(user, role) {
        if (!user) user = this.getParameter('sysparm_user_sys_id');
        if (!role) role = this.getParameter('sysparm_role');
        if (user && role)
            return gs.getUser().getID(user).hasRole(role);
    },
    type: 'HrRoleUtils'

Client Script

if (newValue == 'Yes') {

           var ga = new GlideAjax('sn_hr_core.HrRoleUtils');
        ga.addParam('sysparm_name', 'hasRole');
        ga.addParam('sysparm_user_sys_id', g_form.getValue('assigned_to'));
        ga.addParam('sysparm_role', 'sn_hr_core.u_hr_confidential');


        ga.getXML(function(resp) {
            var response = JSON.parse(resp.responseXML.documentElement.getAttribute('answer'));
            if (response) {
                g_form.clearValue('assigned_to');

            }
        });

The field keeps clearing for users with the role. It doesn't seem to be evaluating properly.

Moving my script to global instead of scoped resolved the issue. Thank you all for your help.
