too much recursion using jquery templates

问题

I'm trying to render a recursive template, but I'm getting a "too much recursion" error...

Can anyone tell what I'm doing wrong here?: code in jsfiddle

Thanks!

EDIT 1 (code added to post):

The HTML

<script id="my_template" type="text/j-query-tmpl">
    <ul class="modules_ul">
        {{each(i, module) modules}}
        <li>${module.mod_name}</li>
        {{if module.sub_modules}}
            {{tmpl "my_template_compiled"}}
        {{/if}}
        {{/each}}
    </ul>
</script>

The JS

var data = {"modules":[
    {
        "id_modules": "1",
        "id_modules_parent": "0",
        "mod_name": "mod 1",
        "sub_modules": [
            {
                "id_modules": "5",
                "id_modules_parent": "1",
                "mod_name": "mod 1a"
            },
            {
                "id_modules": "7",
                "id_modules_parent": "1",
                "mod_name": "mod 1b"
            }
        ]
    },
    {
        "id_modules": "2",
        "id_modules_parent": "0",
        "mod_name": "mod 2",
        "sub_modules": [
            {
                "id_modules": "6",
                "id_modules_parent": "2",
                "mod_name": "mod 2a",
                "sub_modules": [
                    {
                        "id_modules": "3",
                        "id_modules_parent": "6",
                        "mod_name": "mod 2aa"
                    }
                ]
            },
            {
                "id_modules": "4",
                "id_modules_parent": "2",
                "mod_name": "mod 2b"
            }
        ]
    }
]};


$("#my_template").template("my_template_compiled");

$.tmpl("my_template_compiled", data).appendTo("#some_div");

{{tmpl "my_template_compiled"}} was calling the entire modules instead of just the sub-modules. Note the change to your json structure to make recursion possible.
