jquery search textbox if there is a textbox for every checkbox selector

In my project I have a list of ingredients for cooking listed in a checkbox list i have a fixed list and i also give an option to add others if not listed. I have a checkbox with input box next to if for the purpose of adding new ingredients if it is not on the list. I want to add a flag for each input boxc that appears in every checkbox so that when i search the database i know how many textbox i need to generate

So my problem is how to get the textbox if it is available for every checkbox my code is below

$.each($("input[name='ingredients[]']:checked"), function() {
    var othersflag = 0;
    if ($(this).parent().parent().find("input[type='text']")) {
        console.log($(this).parent().parent().find("input[type='text']").val());
        othersflag = "1";
    } else {
        othersflag = "0";
    }
    Ingredients.push({
        ingredients: $(this).parent().find('span').text() || $(this).parent().parent().find('.othersingredientstext').val(),
        othersflag: othersflag
    });
    console.log(Ingredients);
});
