Javascript doesn't working in production - ruby-on-rails

Question

I'm using datatables, a plugin in JavaScript to sort, filter, search... of records in a table.
Searching in some foruns, I saw if I set this line below in config/enviroments/production.rb
config.serve_static_assets = false
to true
config.serve_static_assets = true
worked and really worked.
But I do not do that, because another JavaScripts works and that way is not recommended.
So, I tested another way, I copied all content in datatables.js and cut directly in my view.
The firts line are the firsts line of datatables.js.
<script type="text/javascripts">
(function(i,zap,p){i.fn.dataTableSettings=[]; var D=i.fn.dataTablesSettings;i.fn...
...etc...
$("#ranking").dataTable({
sPaginationType: "full_numbers",
iDisplayLength: 20,
bFilter: true,
aLengthMenu: false,
bLengthChange: false,
bAutoWidth: false,
/* fixa os valores da primeira coluna (index) */
fnDrawCallback: function ( oSettings ) {
/* Need to redo the counters if filtered or sorted */
if ( oSettings.bSorted || oSettings.bFiltered ){
for ( var i=0, iLen=oSettings.aiDisplay.length ; i<iLen ; i++ ){
$('td:eq(0)', oSettings.aoData[ oSettings.aiDisplay[i] ].nTr ).html( i+1 );
}
}
},
aoColumnDefs: [
{ bSortable: false, aTargets: [ 0 ] },
{ aTargets: [ 14 ], bVisible: false }
],
aaSorting: [[ 13, 'desc' ]],
oLanguage: {
sUrl: "/javascripts/i18n/data_tables_lang.json"
}
});
</script>
And again, did not works in production.
I wanna know what does not work in production, well, I copied the code, I'm not using anyother gem like Jammit.
Why does not working?

Answer 1

If that is your exact code, your script tag appears to be incorrect:
<script type="text/javascripts">
should be
<script type="text/javascript">
Remove the "s" from the end of "javascripts," and see if that works.
