Connect button from view to function in controller in MVC

I'm new in MVC and trying to create a site.

My main problem is that I need to activate a function in my controller after clicking a button on the view.

This is my code in the view for the button:

<input type="button" value="Add Star and Role and Categories" onclick="CreateCategoriesID"/>

On the screen in created several checkboxes from list, this is their code:

@foreach (Movies.Models.Category cat in lst)
{
    @Html.CheckBox(cat.ID.ToString()); 
    @Html.Label(cat.Name);
    <br />
}

Each checkbox looks like that:

<input name="5" type="checkbox" value="true">

only their name is different.

In my controller function I need to see which checkbox is clicked, I tried that way:

public void CreateCategoriesID(object sender, EventArgs args)
{
    string catID = "";

    List<Category> lst = entities.Category.ToList();

    foreach (Category cat in lst)
    {
        Request[cat.ID.ToString()].ToString();
    } 
}

This is the function that the button should activate.

The list is equal to the checkboxs list.

Is it the way to get elements from the screen?

How can I check if a checkbox is clicked?

How do I connect the button in the view to the function in the controller?

Thank you in advance!

You've mixed webforms and MVC.

This:

public void CreateCategoriesID(object sender, EventArgs args)

Should be something like

public void CreateCategoriesID(SomeModel model)
{
    // read categories from model, the model may be the categories themselves or a property of it dependent on your data structrue.
}

(Where the form sumbits to {Controller}/CreateCategoriesID)

For how to bind to checkbox lists -
