Let me give you an example of how you can generate inputs via js and simulate a Ubmit of that form:

$( document ).ready(function() {
    
    $("#enviar").click(function(){
      //aqui posso pegar todos os inputs e fazer o que quiser com eles
      //até um for
      console.log(document.getElementsByTagName("input"));
      alert(document.getElementsByTagName("input")[0].value);
    });
    
    $("#saveCurso").click(function(){
      
      nome = $("#inpNomeCurso").val()
      tempo = $("#inpTempoCurso").val()
      area = $("#inpAreaCurso option:selected").text()
      
      var tr = 
            ""+
              "<tr>"+
              "<td><input type'text' id='teste' placeholder='insira algo aqui' /></td><td>"+nome+"</td><td>"+area+"</td><td>"+tempo+" hora</td>"+
              "</tr>"+
            "";
            
      $("#tbody").append(tr);
      
      $("#inpNomeCurso").val("")
      $("#inpAreaCurso").val("")
      $("#inpTempoCurso").val("")
      $('#exampleModal').modal('hide')
    
    });    
    
    
});
#addCurso{
  
  position: absolute;
  right: 0px;
  top: 0px;

}

Notice that part of the code 

$("#enviar").click(function(){
    //aqui posso pegar todos os inputs e fazer o que quiser com eles
    //até um for
    console.log(document.getElementsByTagName("input"));
    alert(document.getElementsByTagName("input")[0].value);
 });
