In the code below, a dojo button is defined. Is it possible to dynamically fire its click event? Thanks if you can provide the hint!

<div id="divAttributeQueryButton">
  <table style="width: 100%;">
	<tr>
          <td style="text-align: center">
	    <button data-dojo-type="dijit/form/Button" data-dojo-props="iconClass:'fa fa-search fa-fw',showLabel:true,disabled:true" data-dojo-attach-point="btnSearch" data-dojo-attach-event="click:onSearch">${i18n.Buttons.search}</button>
          </td>
	</tr>
   </table>
</div>
