this is the code ( this time I've tried it :-) ) in my myapp.pm I had 
package myapp;

use Dancer ':syntax';
use File::Slurp qw(read_file write_file read_dir);
#use db;
use JSON;
use Data::Dump qw/ pp /;
use DBI;
our $VERSION = '0.1';
use Dancer::Plugin::Database;

get '/test' => sub {
    my $jsonobj;
    $jsonobj='[{"name":"test","problem":"here is the problem \" comma 
+"}]';    
    debug $jsonobj;
        template 'test',{passtoserver=> $jsonobj};
};

under the views I had file test.tt 
<!DOCTYPE html>
<html>
<head>
        
</head>
<body>

<div style = "padding: 100px 100px 10px;">
   <script>
   alert('<%passtoserver%>');
   var test='<%passtoserver%>';
   
   alert(JSON.stringify(test));
   alert(JSON.parse(test));
   </script>
  <button type="text" >
</div>

</body>
</html>

I had an error with JSON.parse(test) , when I had browser navigated to http://localhost:3000/test yes your right , when we do that with perl module rather than done by hand is a plus , but teh json file was generated by my website user and I'm just store it in DB , all the work on it just post and get from client and server thanks Rami D.
