CLNDR.js pass variable into underscore.js

I have created a calendar with CLNDR.js. Everything works very well but I want to pass the selected date into Underscore to show only the events day.

Part of my clndr html:

<div class="events-list">
    <% _.each(eventsThisMonth, function(event) { %>

        <!--<% if (event.date == selectedDate) { %>-->

            <div class="event">
                <a href="<%= event.url %>">. <%= event.location %></a>
            </div>

        <!--<% } %>-->

    <% }); %>
</div>

Script:

$(window).load(function(){

$('#mini-clndr').clndr({
    template: $('#calendar').html(),
    events: events,

    clickEvents: {
        click: function(target) {
            if(target.events.length) {

                var selectedDate = target.date['_i'];

                var controls = $('#mini-clndr').find('.controls');                          
                var daysContainer = $('#mini-clndr').find('.days-container');
                var eventsContainer = $('#mini-clndr').find('.events');

                controls.slideUp( "slow" );
                daysContainer.slideUp( "slow" );
                eventsContainer.slideDown( "slow" );

                $('#mini-clndr').find('.x-button').click( function() {
                    controls.slideDown( "slow" );
                    daysContainer.slideDown( "slow" );
                    eventsContainer.slideUp( "slow" );
                });

            }

        }
    },

    adjacentDaysChangeMonth: false

  });
});

Someone can help me? It's the first time I use Underscore.js
