How to get checkbox value from strutcure in template (velocity)

I've a structure in liferay which has a checkbox into a dynamic-element tag (called item_name_1) Now how can i read checkbox value in my template ?

Structure

<dynamic-element dataType="string" indexType="keyword" name="item_name_1" readOnly="false" repeatable="true" required="false" showLabel="true" type="text" width="small">
    <dynamic-element dataType="link-to-page" fieldNamespace="ddm" indexType="keyword" name="content_lnk" readOnly="false" repeatable="false" required="false" showLabel="true" type="ddm-link-to-page" width="small">
        <dynamic-element dataType="boolean" indexType="keyword" name="service_menustat" readOnly="true" repeatable="true" required="false" showLabel="true" type="checkbox" width="">
            <meta-data locale="fa_IR">
                <entry name="label">
                    <![CDATA[منو بصورت پیش فرض باز باشد]]>
                </entry>
                <entry name="predefinedValue">
                    <![CDATA[false]]>
                </entry>
                <entry name="tip">
                    <![CDATA[]]>
                </entry>
            </meta-data>
        </dynamic-element>
        <meta-data locale="fa_IR">
            <entry name="label">
                <![CDATA[اتصال به صفحه]]>
            </entry>
            <entry name="predefinedValue">
                <![CDATA[]]>
            </entry>
            <entry name="tip">
                <![CDATA[]]>
            </entry>
        </meta-data>
    </dynamic-element>
</dynamic-element>

also I tried to get specific checkbox in my template (velocity) using $service_menustat.getData() and $service_menustat.data and even '$service_menustat'

$service_menustat is not exist in template intellisense..

Thanks
