I find solution of my problem! I replace create button if I use project.project model.
1) I create some js script (static/src/js/task_list.js) with click listener for my button :
  
openerp.project = function (instance){       

        var QWeb = openerp.web.qweb;
        _t = instance.web._t;
        var self = this;
        openerp.web.ListView.include({       

                load_list: function(data) {           

                                       this._super(data);
                                       if (this.$buttons) {               

                                                  this.$buttons.find('.oe_new_button').off().click(this.proxy('do_the_job')) ;
                                                  console.log('Save & Close button method call...');
                                      }       

                                                      },       

                                     do_the_job: function () {           

                                               this.do_action({               

                                                        type: "ir.actions.act_window",               

                                                        name: "Создание нового проекта",               

                                                        res_model: "project.project",               

                                                        views: [[false,'form']],               

                                                        target: 'current',               

                                                        view_type : 'form',               

                                                        view_mode : 'form',               

                                                        flags: {'form': {'action_buttons': true, 'options': {'mode': 'edit'}}}});
                                              return { 'type': 'ir.actions.client',                    'tag': 'reload', } } });
    }    

2) After that I create static/src/xml/project_button.xml with template, which replace "Create" button if I use project.project model

<?xml version="1.0" encoding="UTF-8"?>

    <template id="template" xml:space="preserve">       

          <t t-extend="ListView.buttons">                   

                 <t t-jquery="button.oe_list_add" t-operation="replace">                           

                          <button t-if="widget.model == 'project.project'"  class="oe_button oe_new_button oe_highlight" type="button">Создать новый проект</button>                           

                          <button t-if="widget.model != 'project.project'" class="oe_button oe_list_add oe_highlight" type="button">Создать</button>           

                </t>       

          </t>   

</template>

3) After that I add my js script in web.asset_backend (I create file project/views/project.xml)

<?xml version="1.0" encoding="utf-8"?>   

<!-- vim:fdn=3:
    -->   

          <openerp>       

                 <data>           

                       <template id="assets_backend" name="project assets" inherit_id="web.assets_backend">               

                             <xpath expr="." position="inside">                   

                                  <script type="text/javascript" src="/project/static/src/js/task_list.js"></script>               

                             </xpath>           

              </template>       

         </data>   

</openerp>

4) And finally I add in project/\_\_openerp__.py section 'qweb' for static/src/xml/project_button.xml, 'js' for static/src/js/task_list.js and place file views/project.xml in 'data' section.

'data': [           

'security/project_security.xml',            

...
'views/project.xml',       

],       

'qweb': ['static/src/xml/project_button.xml',],       

...
 'js': 'static/src/js/task_list.js',

And my button successful replace old button in project.project model.
