    clientContext.executeQueryAsync(DeleteCustomAction, OnQueryFailed);
}

function DeleteCustomAction()
{
    var customActionEnumerator = collUserCustomAction.getEnumerator();

    while (customActionEnumerator.moveNext()) 
    {
        var oUserCustomAction = customActionEnumerator.get_current();

        if (oUserCustomAction.get_title() == 'ITSD Admin1') 
        {
           oUserCustomAction.deleteObject();
       clientContext.load(oUserCustomAction);
       clientContext.executeQueryAsync(OnQuerySucceeded,OnQueryFailed);
