Your datas is array with only one element - array with models. You have to update your template replacing datas with datas[0], or store it in var and pass it into loop
<ul class="table-view">
<% _.each(datas[0], function(schedule, key) { %>
<li class="table-view-cell">
<a href="#enter-reading/<%= key %>"
class="push-right"><%= schedule.time %></a>
</li>
<% }); %>
</ul>
