How can I make sure my text entry box only appears when I click on the answer that has a entry box?

Hi I am trying to make sure that my text entry box only appears when I click on the option that has an entry box. I have a code that works for a multiple answer type of question but it does not work for a single answer type of questions. See below the Java Scrip.

Qualtrics.SurveyEngine.addOnload(function()
{
/*Place your JavaScript here to run when the page loads*/

});

Qualtrics.SurveyEngine.addOnReady(function()
{
/*Place your JavaScript here to run when the page is fully displayed*/
jQuery('input:text').hide();
  jQuery("[type='checkbox']").change(function(){
    if(jQuery(this).prop("checked") == true){
    var v1 = jQuery(this).attr("id");
    jQuery("[id*='"+v1+"~TEXT']").show();
    }else{
    var v1 = jQuery(this).attr("id");
      jQuery("[id*='"+v1+"~TEXT']").val('');
    jQuery("[id*='"+v1+"~TEXT']").hide();
    }

  });
});

Qualtrics.SurveyEngine.addOnUnload(function()
{
/*Place your JavaScript here to run when the page is unloaded*/

});

Thanks,
