You're replacing using regular expressions, and $ is a regular expression reserved special character for end of line/string.

You need to escape the $ by preceding it with a backward slash \ to make it hit its literal character:

if (html.indexOf('$txt$') > -1) {
    html = html.replace(/\$txt\$/ig, '<input type=text></input>');
}

all you need to do is escape the $ sign since it has a meaning in a regular expression. Change it to 

html = html.replace(/\$txt\$/ig, '<input type="text" />');

and it should be fine :)

edit: $ means end of line in a regular expression :)
