How can I use C# Script to call JS Script in Unity iPhone?

I use C# to develop my game in Unity iPhone, but I use iTween(JS version) to Deal with animation of GUI,now question is how can I call iTween(JS version) in C#, my code is:

using UnityEngine;
using System.Collections;

public class UITest : MonoBehaviour 
{

    void Awake()
    {

    }

    // Use this for initialization
    void Start () 
    {

        iTween.moveTo(gameObject, {"x":0.5, "time":0.5, "delay":1.5});
    }

    // Update is called once per frame
    void Update () 
    {

    }
}

But it's wrong,the wrong message is: Assets/CSharp/UITest.cs(24,43): error CS1026: Expected ',' or ')'

if I change code to this:

 using UnityEngine;
using System.Collections;

public class UITest : MonoBehaviour 
{

    void Awake()
    {
    }

    // Use this for initialization
    void Start () 
    {
        Hashtable ht = new Hashtable();
        ht.Add("x", 0.5);
        ht.Add("time", 0.5);
        ht.Add("delay", 1.5);

        iTween.moveTo(gameObject, ht);
    }

    // Update is called once per frame
    void Update () 
    {

    }
}

The wrong message is disappear,But It's has new wrong message when I install my program into iPhone. The wrong message is:

I have crazy!!!!!!!

My C# is in Asset/CSharp,iTween(JS version) is in Asset/Plugins. Help!!!!!!!!

Why don't you just use the C# version of iTween? http://www.insquare.com/itween/

Also, the reason this line doesn't work in c#:

iTween.moveTo(gameObject, {"x":0.5, "time":0.5, "delay":1.5});

Is because C# can't create Hashtables like that.

I use iTween(C# version) in my program first, but It's doesn't work.The wrong message is:

Assets/Plugins/iTween.cs(308,20): error CS1041: Identifier expected

I find the question is `public List beziers;` in iTween.cs, I cann't solved it, so I use iTween.js,But it has other question.
