title: ModelForm not saving BooleanField default value
body: <p>I have the following Model:</p>
  
  <pre><code>class TransType(models.Model):
      typeName = models.CharField(max_length=200)
      isActive = models.BooleanField(default=True, blank=True)
  
      def __str__(self):
          return self.typeName
  </code></pre>
  
  <p>Whenever I am creating a new object without specifying isActive value, it is saving the object with isActive set to false even though I have set the default to True. What could be the issue here?</p>
  
  <p>EDIT: </p>
  
  <pre><code>&lt;form method="POST" action="{% url 'trans:createmode' %}" class="modal-content form-horizontal" id="creator"&gt;
    {% csrf_token %} {{ form }}
    &lt;label for="mode" class="col-sm-3 control-label"&gt;Transport Mode&lt;/label&gt;
    &lt;input type="text" name="typeName" maxlength="200" class="form-control" required="required" id="typeName"&gt;
    &lt;input type="submit" class="btn btn-fill btn-success pull-right" id="submit" value="Save"&gt;
  &lt;/form&gt;
  </code></pre>
