ejs template function inside function

Is there a way for ejs template to call a function inside another function? For example I am trying to do like this:

<% function graph(graph) { %>
        <a href="<%= graph.href %>"><%= graph.description %></a>
<% } %>


<% function point(point) { %>

    <Placemark id="<%= point.id %>">
        <description>
        <%= point.Apibudinimas %> <%= point.IP %>
        <![CDATA[

        <% graphs.map(graph) %>

        ]]>
        </description>
    </Placemark>

<% } %>

But it says that graphs are undefined...
