You really should use an HTML parser to handle this job, but the following regular expression and substitution "trick" might just be robust enough to handle your data:
use strict;
use warnings;
my $data = do { local $/; <DATA> };
$data =~ s/
(<input.*?ng-model=")
([^[]+)
(\[\d+\]")
(.*?)
/
$1
. $2
. $3
. qq( label="@{[ (split '\.', $2)[-1] ]}")
. $4
/exgs
;
print $data;
__DATA__
<input type="checkbox"
ng-model="data.mydebts.loan[0]"
<input type="checkbox"
ng-model="foo.bar.baz.qux[2]" />
<input type="checkbox"
ng-model="foo[300]" >
Results:
<input type="checkbox"
ng-model="data.mydebts.loan[0]" label="loan"
<input type="checkbox"
ng-model="foo.bar.baz.qux[2]" label="qux" />
<input type="checkbox"
ng-model="foo[300]" label="foo" >

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
