glfw and mouse pressed

OpenGL OpenGL: Basic Coding
1

i have this code :


    while (!glfwWindowShouldClose(window))
    {
        /* Render here */
        m_rend->Render();
        /* Swap front and back buffers */
        glfwSwapBuffers(window);

        /* Poll for and process events */
        glfwPollEvents();
        if (glfwGetMouseButton(window, GLFW_MOUSE_BUTTON_1) == GLFW_PRESS)
        {

            m_rend->mousePressed();
        }
        if (glfwGetMouseButton(window, GLFW_MOUSE_BUTTON_1) == GLFW_RELEASE)
        {

            m_rend->mouseReleased();
        }
        
    }

I use glfw
but the release event starts immediatily after press the mouse button:
1)press the button
2)mousepressed is down
3)after 1 sec mouse button is released and i continue to push the button.
I tried with this poll mode and callback but the result is the same .
where i wrong?
