title: Display data when click on button with Meteor
body: <p>I have one button, when I click I want to display data only if the value of the checkbox is true, If it false, it's display when DOM is created
  But I can't please look my code. </p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>Template.students.helpers({
    all_students: () =&gt; {
      return students.find();
    }
  });
  
  Template.body.onCreated(() =&gt; {
    Meteor.subscribe('students');
  });
                  
  Template.students.events({
    'submit .insert': (e) =&gt; {
      e.preventDefault();
      students.insert({
        name: e.target[0].value,
        age: e.target[1].value,
        check: false
      });
      this._checkValue(e);
    },
    'click .is-delete': (e) =&gt; {
      students.remove(e.currentTarget.id);
    },
    'click .check-checkbox': (e) =&gt; {
      students.update(e.currentTarget.id, {
        $set: {
          check: !this.check
        }
      })
    },
    'click .all': () =&gt; {
      // HERE
    }
  })</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;template name="students"&gt;
    &lt;div class="content menu"&gt;
      &lt;ul&gt;
        &lt;button class="ui button all"&gt;All list&lt;/button&gt; &lt;!-- THIS BUTTON --&gt;
        {{#each all_students}}
          &lt;li class="content-list" id="{{ _id }}"&gt;
  
            &lt;div class="name"&gt;{{ name }}&lt;/div&gt;
            &lt;div class="age"&gt;{{ age }} ans&lt;/div&gt;
            &lt;span id="{{ _id }}" class="delete is-delete"&gt;&lt;/span&gt;
            &lt;div class="ui checkbox"&gt;
              &lt;input id="{{ _id }}" class="check-checkbox" type="checkbox" name="check"&gt;
            &lt;/div&gt;
          &lt;/li&gt;
        {{/each}}
      &lt;/ul&gt;
    &lt;/div&gt;
  &lt;/template&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>Inside of my event handler <code>click .all</code> if I try to <code>return students.find()</code> it doesn't work. </p>
