Submit data is only received in the first tab

I have the following code used to divide 2 tabs, one tab to submit data using Ckeditor, one tab to save data using Codemirror.

    <div class="form-group">
        <label class="form-label" asp-for="Content"></label> <span asp-validation-for="Content"></span>
        <div class="controls">
            <div class="nav-tabs-outer">
                <ul class="nav nav-tabs js-tabs">
                    <li class="active text-center"><a href="#tab1" data-toggle="tab">TAB1</a></li>
                    <li class="text-center"><a href="#tab2" data-toggle="tab">TAB2</a></li>
                </ul>
                <div class="tab-content">
                    <div id="tab1" role="tabpanel" class="tab-pane active fade in">
                        <textarea id="ricktextContent" seo-page-content class="form-control form-control-t" rows="3" placeholder="Mô tả" asp-for="Content"></textarea>
                    </div>
                    <div id="tab2" role="tabpanel" class="tab-pane fade in">
                        <textarea id="ricktextContentDiv"  class="form-control form-control-t" rows="3" placeholder="Mô tả" asp-for="Content"></textarea>
                    </div>
                </div>
            </div>
        </div>
    </div>

and I have the following js snippet to add and edit data

var _page = 1;
$(function () {
    $("[search-advance]").toSearch();
    $("[button-popup]").toPopup();
    $("[button-open-file-manager]").toButtonOpenFile();
    $("[button-submit]").toSubmit(null, null, function () {
        onRefeshValue();
    });
    $("[button-delete]").toDelete();
    $("[button-post]").toPost(null, null, function () {
        onRefeshValue();
    });
    getDataGrid(1, true);
});
var cm1;


function initRickText() {
    cm1 = CodeMirror.fromTextArea(document.getElementById("ricktextContentDiv"), {
        lineNumbers: true,
        mode: "text/html",
        matchBrackets: true,
        lineWrapping: true,
        autoRefresh: true
    });

    $("ricktextContent").toRickText({ customConfig: 'configRickText.js', filebrowserImageBrowseUrl: "@Url.Action("Manager", "FileManager", new { area = "Base", path = "Blog/" })" });
    $("[button-update-status]").toPost(function (rs, $this) {
        swal({
            title: "Thông báo!",
            text: rs.message,
            type: rs.type,
            confirmButtonText: "Đóng!"
        });
        setTimeout(function () {
            $this.button('reset');
            setTimeout(function () {
                statusButtonEdit(false);
            }, 200);
        }, 300);
        coSoYTeId
    }, function () {
        return serializedData;
    });
}

function onRefeshValue() {
    document.getElementById("ricktextContentDiv").value = cm1.getValue();
}
function getDataGrid(page, first = false) {
    _page = page;
    $("[grid-index]").toGridView(first, page, function () {
        if (decodeURIComponent(location.hash.substr(1)) == "openPopup") {
            try {
                // $("[data-open-edit]")[0].click();
                const fullUrl = window.location.href;
                const url = new URL(fullUrl);
                const code = url.searchParams.get("code");
                const language = url.searchParams.get("language");
                if (!code || !language) {
                    return
                }
                const hidePopup = $("#edit-by-code-and-language").attr("href", `/Admin/Manager/StaticInformationManager/EditByCodeAndLanguage?language=${language}&code=${code}`);
                hidePopup.click();
            } catch (e) {
                console.log(e);
            }
        }
    });
}
function reGetDataGrid(e) {
    if (e != null) {
        _page = 1;
        $("[name='language']").val($(e).attr("data-val"));
    }
    getDataGrid(_page, false);
}
function onRefesh() {
    cm1.refresh();
};

Now i am facing the error that when i add data i can only add with , means adding with Ckeditor, but adding with Codemirror will be null, I think it’s because of the ordering because when I set first, meaning Codemirror will be in the first tab so it will only add gets data using Codemirror and Ckeditor will be null.
I tried a few ways but they didn’t work very well. I hope everyone can suggest some solutions for me. Sincerely thank

I just want to be able to submit data using both ckeditor and codemirror, not just one of the two
