Select chage not work!

Select chage not work!

Hello, this is my first post!

I have this select in my HTML:

<select style="border: 1.5px solid rgb(170, 169, 169); width: 137px;" id="tx_tipo_lavagem1" name="tx_tipo_lavagem1" class="tx_tipo_lavagem" onchange="onSelectChange(this);">
                  <option value="1">Seco</option>
                  <option value="2">Úmido</option>
            </select>


And my JQUERY code is this:

$("#tx_tipo_lavagem1").change(function(){
      alert('asd');
   });


But the alert never happens!
Some help?
Thanks for all help and atention!
