Automatic sizing of HTML.TextAreaFor based on content

I have an MVC 5 project with Bootstrap, and a form that relies upon the model for its field content. There are many fields which need to be textareas, to allow up to 255 characters; but I don't want to take up space unnecessarily. Ideally the textarea would begin with a single line, and grow as text is added via data entry (and shrink back as text is deleted).

                <div class="form-group row">
                    <div class="col-md-4">
                        <label>@Html.DisplayNameFor(model => model.FundAgreements)</label>
                    </div>
                    <div class="col-md-8">
                        @Html.TextAreaFor(model => model.FundAgreements, 1, 100, new { htmlAttributes = new { @class = "form-control" } })
                        @Html.ValidationMessageFor(model => model.FundAgreements)
                    </div>
                </div>

When I had a simple HTML5 form, without Bootstrap, I was able to use the below in $(document).ready for <textarea>, but so far have been unable to modify it successfully to work with Html.TextAreaFor.

 <textarea id="FundAgreements" class="intake-textarea" rows="1" maxlength="255"></textarea>

Select allOpen in new window

// Auto resize textarea based on text entered
function resizeTextArea() {
    $(".intake-textarea").keyup(function(e) {
        $(this).height(30);
        $(this).height(this.scrollHeight + parseFloat($(this).css("borderTopWidth")) + parseFloat($(this).css("borderBottomWidth")));
    });
}
