http://cordova.apache.org/docs/en/3.3.0/cordova/contacts/contacts.create.html

or you can search the plugin in the 

<plugin name="cordova-plugin-contacts"            source="npm" spec="~2.0.1" />

Add this to your config.xml

document.addEventListener("deviceready", onDeviceReady, false);

    function onDeviceReady() {

        var myContact = navigator.contacts.create({"displayName": "Test User"});

        myContact.note = "This contact has a note.";

        console.log("The contact, " + myContact.displayName + ", note: " + myContact.note);

    }

This will create a contact test user in your mobile phone
