Proper way to translate sentence with variable

passing_options_to_localize.md

Modifying element's attribute does not work.

    is.displaySearchResult = function(count) {
        $('#searchResult')
            .attr("data-i18n", "candidateFilter:searchResult")
            .attr("data-i18n-options", '{ "count": ' + count + ' }')
            .localize();
    };

Passing the data-i18n-options as options of localize.

    is.displaySearchResultNew = function(count) {
        $('#searchResult')
            .attr("data-i18n", "candidateFilter:searchResult")
            .localize({ count: count});
    };
