Modal box not show after form validation check

Question

I have a registration form and in this form, I give validation to some input fields required . After the validation check, I want to open a modal box $('#exampleModal').modal('show'); but it's not working

Code:

<form class="well form-horizontal"   id="contact_form" autocomplete="off">
<fieldset>
<legend><center><h2><b>Registration Form</b></h2></center></legend><br>
<div class="form-group">
  <label class="col-md-4 pd-r control-label">firstname</label>  
  <div class="col-md-4 pd-r inputGroupContainer">
  <div class="input-group">
   <input  name="first_name" id="first_name"  class="form-control tboxs"  type="text" minlength="4" required>
  </div>
  </div>
</div>

<div class="form-group">
  <label class="col-md-4 pd-r control-label">village</label> 
    <div class="col-md-4 pd-r inputGroupContainer">
    <div class="input-group">
     <input name="village" id="village" class="form-control tboxs" type="text" required>
    </div>
  </div>
</div>

<div class="form-group">
  <label class="col-md-4 pd-r control-label"></label>
  <div class="col-md-4 pd-r"><br>
    <button type="submit" value="submit" class="btn-theme-colored btn">SUBMIT <span class="glyphicon glyphicon-send"></span></button>
  </div>
</div>

</fieldset>
</form>
<!-- Modal -->
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel"><font color="black"><strong>Verify OTP</strong></h5>
      </div>
      <div class="modal-body">
         <form method="POST"  id="otp_form" action="">
            <div class="row">
                <div class="col-sm-12 form-group">
                    <input type="text" class="form-control tboxs" id="otp_data" name="otp_data" placeholder="Enter OTP" maxlength="4" required="">
                </div>
            </div>
             <div class="row">
                <div class="col-sm-12 form-group">
                    <button type="submit" name="verifyotp" class="btn btn-lg btn-info btn-block">Verify</button>
                </div>
            </div>
          </form>
      </div>
    </div>
  </div>
</div>

Script:

<script type="text/javascript">
$('#submit').click(function(){
   if($('#first_name').val()==''){
      alert('Name can not be left blank and atleast 4 char long');
      return false;
    }
   if($('#village').val() == ''){
      alert('village can not be left blank');
      return false;
   }
   $('#exampleModal').modal('show');
   return true;
});
</script>

In the code, validation is working after the validation check modal box not open. I do no know where I am wrong in code.

Here is you updated script and html code

Issue with HTML code:

• Button type was submit but you are calling click event on it
• You didn't assigned id to particular button eg: id='submit'

 $('#submit').click(function(){ if($('#first_name').val() == '' ){ alert('Name can not be left blank and atleast 4 char long'); return false; } if($('#village').val( ) == '') { alert('village can not be left blank'); return false; } $('#exampleModal').modal('show'); return true; });
