I am getting a SyntaxError: Unexpected EOF output when using an underscore template to render html in a Backbone application. Here is my template:-

<script type=text/template id=shellmenu-template>

  <div>

    <p>menu template html will go here....</p>

    <div class=menuButtonsContainer>

        <% _.each(menu, function(menuItem){ %>

        <button class=menuButton id=<%= _.escape(menuItem.id)><%= _.escape(menuItem.title) %></button>

        <% }); %>

    </div>

  </div>

</script>

It is specifically erroring on this part:-

id=<%= _.escape(menuItem.id)

The id attribute is a number, here is the menuItem object:-

dataPath: 

helpType: default

id: 0

moduleName: TestModule

modulePath: interaction/test/testmodule

title: Test Module Interaction

I have tried making the id a string or making it the title attribute in the underscore template code just to see if I can get a test case working in any shape or form but I am stumped so far. I have a similar template doing pretty much the same thing with no errors.

Any ideas what silliness I am engaging in to cause this? :-)
