problems with ajax form

Hi everyone! A few days I can't resolve a task. I want to build a single
page app without any page refresh. So I have a button 'Add', onclick it
inserts in a DOM a simple remote:true form and when I try to submit this
form - nothing happens BUT if i refresh the page - it works. Guess some
handler is absent but not sure. Advise please. Here's my form
<%= form_tag(:add_task, method: 'post', remote: true) do %>
            <td>
              <span class="glyphicon glyphicon-plus"></span>
            </td>
            <td>
              <%= text_field(:task,:project_id,type: 'hidden',value:
@project.id)%>
              <%= text_field(:task,:name,class: 'form-control
task_field', placeholder: 'Start typing here to create a task...')%>
            </td>
            <td>
              <%= button_tag('Add task',class:'btn btn-add_task') %>
            </td>
        <% end %>

The first thing to do is to look in development.log and see if it
submitting correctly.

already checked. nothing written in the log

When replying please quote the previous message, this is is a mailing
list not a forum (though you may be using it via a forum like
interface). If you don't we have to look back through previous
messages to find what you are replying to.

I presume that you mean that when you press the button absolutely
nothing happens at the server. In that case your submit button is not
working.

I notice that you seem to have a form that is a single row in a table,
that is not valid html. A form can wrap a complete table or exist
within a cell, but not wrap part of a table. That may or may not be
the problem you are seeing, but you must fix that first. Even if it
appeared to work it may not work in a different browser or a different
version of the same browser.
