Jira renderer plugin doesn't show up

[Laci R]

I am having this lines in my atlassian-plugin.xml

<jira-renderer key="jira-source-table-sort-renderer" name="Table Sort Renderer"
               class="extension.customfields.renderer.TableSortRenderer">
    <description>A renderer that will renderer multitext field table with sorting</description>
    <resource type="velocity" name="edit"
              location="templates/plugins/renderers/wiki/wiki-renderer-edit.vm"/>
</jira-renderer>

but it won't show up in Field Configurations as Renderer for custom field. I have one more in atlassian and that shows up. Can you point me where am I wrong? Also tried system=true to parameters.
