When using ASP.NET WebForms I always try and stay away from referring to IDs in my javascript because the rendered ID may not always be the same as the server side ID.

Use CssClass to ensure consistency, and a . prefix instead of # prefix in your jquery selector.

TextBox t = new TextBox();
t.ID = "txtDynamic";
t.TextMode = TextBoxMode.MultiLine;
t.Rows = 7;
t.CssClass = "limit140";

$('.limit140').limit('140','#charsLeft');
