Clear textboxes to 0 in ASP.NET using jquery from code behind

Question

I want to clear all the textboxes to 0 that are in my divData. If want to clear all the textboxes in the page I used the first line of code below. But I only want to clear what is inside the div. Am I missing something ?

protected void ResetTextboxes()
{
       //This Works fine but it clears all the textboxes on the page
       // string jquery = "$('input[type=text]').val('0');"; 

        //Can't get this to work. This does not clear textboxes in divData only
        string jquery = "$('#divData input').val('0');";

        ClientScript.RegisterStartupScript(typeof(Page), "a key",
        "<script type=\"text/javascript\">" + jquery + "</script>");


  }

I got it working. Since the page is attached to a MasterPage, I had to append the ContentPLaceHolder ID plus the ID of the Div used in the child page.

 protected void ResetTextboxes()
 {

        string jquery = "$('#MainContent_divData input[type=text]').val('0');";

        ClientScript.RegisterStartupScript(typeof(Page), "a key",
        "<script type=\"text/javascript\">" + jquery + "</script>");          
  }
