Error using monaca contact plug-in

I'm going to use the contact plug-in in monaca, and I'm going to follow the example code.

<script>
function contacts_success(contacts){
    alert(contacts.length)
        + 'contacts returned.'
        + ( contacts [2] & contacts [2].name ?
              ('Third contact is' + contacts[2].name.formatted):
              ''));
}
function contacts_failed(msgObject){
    alert("Failed to access contact list:" + JSON.stringify(msgObject)));
}
function get_contacts(){
    varobj = new ContactFindOptions();
    obj.filter="";
    obj.multiple=true;
　  navigator.contacts.find(
        ["displayName", "name", contacts_success,
        contacts_failed, obj);
}
</script>
</head>
<body>
    <a href="#" class="btn large" onclick="get_contacts();return false;">Get Phone's Contacts</a>
</body>

was successfully executed.I want to do this when it boots up.

<script>
function contacts_success(contacts){
    alert(contacts.length)
        + 'contacts returned.'
        + ( contacts [2] & contacts [2].name? ('Third contact is' + contacts [2].name.formatted)
                : ''));
}
function contacts_failed(msgObject){
    alert("Failed to access contact list:" + JSON.stringify(msgObject)));
}

varobj = new ContactFindOptions();
obj.filter="";
obj.multiple=true;
navigator.contacts.find(
    ["displayName", "name", contacts_success,
    contacts_failed, obj);
</script>

but

Uncaught ReferenceError: ContactFindOptions is not defined

The error occurred.
I wonder why...

ContactFindOptions This may be because the process runs before loading the file (Cordova) that defines it.

// Wait for Cordova to finish loading
//
document.addEventListener("deviceready", onDeviceReady, false);

// Cordova Ready
//
function onDeviceReady() {
    varobj = new ContactFindOptions();
    obj.filter="";
    obj.multiple=true;
    navigator.contacts.find(
        ["displayName", "name",
        contacts_success, contacts_failed, obj);
}

and so on.
