Not trigger form validation on button click

Question

I have a form which consists of two buttons. None of them have the "submit" declaration in type.

My issue is that the form validation is triggered during both button button clicks where as I want the validation only to happen on one particular button click. Can this be achieved?

Below is my code.

<form class="form-horizontal" ng-controller="checkoutCtrl" name="ordersubmitform">
  <div class="panel panel-default" ng-init="init()">
    <div class="panel-body">
      <div class="row">
        <div class="col-md-6">
          <fieldset>
            <legend class="text-semibold">PERSONAL INFO</legend>
            <div class="form-group">
              <label class="col-lg-3 control-label">Name</label>
              <div class="col-lg-9">
                <input type="text" ng-model="customer.name" name="username" class="form-control" required/>
              </div>
            </div>
            <div class="form-group">

              <div class="col-lg-9">
                <input type="email" ng-model="customer.email" name="email" class="form-control" required />
              </div>

Answer 1

Add type to the button:

<button>I submit by default</button>
<button type="button">I don't submit</button>
<button type="submit">I do</button>
