Loading handlebars.js template from external html file shows nothing

This question is a bit of a stretch of my JS skills, so I might explain it like an idiot.

Here is my JavaScript to get the json from the server, and try to push it into a template:

    //Server Interface Start
//Access the web api for The User:
var lucidServer = (function () {
    //global error handler
    $(document).ajaxError(function (event, xhr) {
        alert(xhr.status + " : " + xhr.statusText);
    });
    //client Calls
    var getClients = function (id) {
        return $.ajax(clientUrl + "/list/" + id)
    };
    var getClient = function (id) {
        return $.ajax(clientUrl + "/details/" + id)
    };

    //push them out to the world!
    return {
        getClients: getClients,
        getClient: getClient,
    };
}());
//Server Interface End

(function () {
    //list of clients
    var refreshClients = function () {
        lucidServer.getClients(1).done(showAllClients);
    };
    var showAllClients = function (templateInput) {
        var source;
        var template;
        var path = '../Templates/indexTemplates.html'
        $.ajax({
            url: path,
            cache: true,
            success: function (data) {
                source = data;
                template = Handlebars.compile(source);
                $('#clientListOutput').html(template(templateInput));
            }
        });
    };
    $(function () {
        refreshClients();
    });
}());

GetClients works fine and returns the Json data I am expecting. When I inspect the templateInput it is showing what I expect.

Here is the external template:

<script id="clientList" type="text/html">

<div id="clients">
    {{#each client}}
                <span data-id="{{this.iD}}" />
    <div>
        <p>{{this.iD}}</p>
        <p>{{this.name}}</p>
    </div>
    {{/each}}
</div>
</script>

What I am ultimately aiming to do is hold either all my templates in one html file that I can call by script id, or have each template be its own file that I can call. When I run this page nothing is showing up, there's no error or anything. Here is the entire index page:

Edit

I changes the way my template looks slightly. Through debugging the js in Chrome tools it is telling me that 'data' is undefined in the ajax success line within showallclients.

You need to call template with the data returned from getClient. In you example the argument to showAllClients is shadowed by the argument in the success callback because you use the same name (data). Change the argument name in showAllClients to something else, and pass it to the template function.

(function () {

        //list of clients
        var refreshClients = function () {
           $.when(lucidServer.getClients(1)).done(showAllClients);
        };
        var showAllClients = function (templateInput) {
            var source;
            var template;
            var path = 'Templates/indexTemplates.html'
            $.ajax({
                url: path,
                cache: true,
                success: function (data) {
                    source = data;
                    template = Handlebars.compile(source);
                    $('#clientListOutput').html(template(templateInput));
                }
            });
        };

        $(function () {

            refreshClients();
        });
    }());

EDIT:

In the template you need to refer to this inside the each block:

<div id="clients">
    {{#each client}}
                <span data-id="{{this.id}}">
                    <div>
                        <p>{{this.iD}}</p>
                        <p>{{this.name}}</p>
                     ...
                    </div>
        {{/each}}
</div>

In your example you use nested iterators, which I'm not sure is supported. Please read How do I use nested iterators with Mustache.js or Handlebars.js? or Ember.js / Handlebars nested each iterations for a different approach.
