Beamer: Change only several bullets in the list

Question

I would like to change the bullets in the second itemize to arrows.

\begin{alertblock}{The Aim of this Research} 
    \begin{itemize}
        \item Item 1
        \item Item 2
            \begin{itemize}
                \item Item 2-1
                \item Item 2-2
            \end{itemize}
    \end{itemize} 
\end{alertblock}

Form above, I would like to make:

・Item 1 
・Item 2
   => Item 2-1  (change bullet to arrow)
   => Item 2-2

I've tried inserting \renewcommand{\labelitemii}{$\rightarrow$} before and after the second \begin{itemize} and the solution in this question, but they don't work.

Do you want to do this for all items at this level or for individual ones? For individual items see How to get larger item symbols for some lists in a Beamer presentation? or Change item symbol within itemize in beamer. For all items see Change bullet style / formatting in Beamer. One of these is probably a duplicate of your question. — Alan Munn, Feb 15 '16 at 18:04

You can define your bullet symbols direct in the itemization:

\begin{itemize}
   \item[$\rightarrow$] Item 1
\end{itemize}

This can become tedious if this should be done more than once. Did you test it, by the way? – Feb 15 '16 at 18:17
Yes, but i think for two items it's ok. Yes, I have tested it, should i post my MWE? – Carina Feb 15 '16 at 18:22

If you wish to change the second level of all itemize lists, you can adjust the symbol associated with the itemize subitem template:

\documentclass{beamer}

\let\Tiny\tiny% http://tex.stackexchange.com/a/94159/5764

\setbeamertemplate{itemize subitem}{$\rightarrow$}

\begin{document}

\begin{frame}
  \frametitle{Frame title}

  \begin{alertblock}{The Aim of this Research} 
    \begin{itemize}
      \item Item 1
      \item Item 2
        \begin{itemize}
          \item Item 2-1
          \item Item 2-2
        \end{itemize}
    \end{itemize} 
  \end{alertblock}
\end{frame}

\end{document}
