Calendar icon button submitting form

[fairking]

Got the following html:

<form @submit.prevent="formSubmit">
  // Some other fields
  <Calendar id="from_date" v-model="item.fromDate" date-format="dd.mm.yy" :step-minute="15" :showTime="!item.allDay" :showIcon="true" />
  <Button :label="Save" type="submit" class="pull-right" style="width:auto;" />
</form>

and the typescript:

  methods: {
    formSubmit() {
      // Save the form
    }
  }

Apparently if I click the Calendar button it triggers the formSubmit method.

These buttons submit form as well:
