Repeater bind user control event

Question

I have a web user control with a repeater and inside the repeater i have a dynamic number of radiobuttons, On page_load i am trying to call the onDataItemBound event of the repeater to find the radiobuttons and binding the oncheckedchanged event to a method in my code but cant get it to work, here is my code:

protected void Page_Load(object sender, EventArgs e)
{
    Repeater_Select.ItemDataBound += Repeater_Select_OnItemDataBound; 
}


protected void Repeater_Select_OnItemDataBound(object sender, RepeaterItemEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
    {
        var customRbtn = (CustomRadioButton)e.Item.FindControl("RadioButton_Select");
        customRbtn.CheckedChanged += RadioButton_Select_OnCheckedChanged;
    }
}

I've managed to solve my problem, the problem was that i have another method being called before this OnItemDataBound which called DataBind() on the repeater, so I simply reversed the order and put the call for OnItemDataBound before the other method like so:

    protected void Page_Init(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            BindRadioOnChecked();
        }
    }

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            GetFeaturePackData();
        }
    }

    private void BindRadioOnChecked()
    {
        foreach (RepeaterItem item in Repeater_Select.Items)
        {
            if (item.ItemType == ListItemType.Item || item.ItemType == ListItemType.AlternatingItem)
            {
                CustomRadioButton customRbtn = (CustomRadioButton)item.FindControl("RadioButton_Select");
                customRbtn.CheckedChanged += RadioButton_Select_OnCheckedChanged;
            }
        }
    }

Now it's inside Page_Init so fires before Page_Load
