I have set the system up in model admin and it works. I just need help figuring out how to do a ajax type search on the postal codes field. See existing code below:

class Insurer extends DataObject
static $db = array

static $has_one = array(

function getCMSFields() {
$fields = new FieldList(
new TextField('Name','Company Name'),
$dateField = new DateField('DateJoined', 'DateJoined',date("Y-m-d")),
new TextField('Tel','Telephone Number'),
new TextField('Fax','Fax Number'),
new TextField('VatNo','Vat Number'),
new TextareaField('PostalAddress','Postal Address'),
new CheckboxField('IsActive', 'Is this insurer active?',1),
new DropdownField('PostalCode', 'Postal Code', PostalCode::get()->map('ID', 'Suburb')) /// How do i make this a ajax search
$dateField->setConfig('showcalendar', true);

return $fields;

// Sets the sumary fields that will be displayed in teh grid field
static $summary_fields = array(
