How to call Redux store changes in single component?

Question

I have a <Category /> component. Redux Router pases all the category/ urls inside it. The problem is with store update. I am setting CategoryContent store with initial values in componentDidMount(), but when i am navigating from category to category, it uses the same component, so i cant chage my CategoryContent store in this hook. I also cant call it in my render function. So what is the right way to change my store, when i am navigating my site? Maybe there is some hoot on url change or something?

<DefaultPage path="/category" component={Category} />

so every category is set will use my Category component. When i go to /category I am dispatching an action to load a content by calling loadPageContent():

const mapDispatchToProps = dispatch => {
    return {
        loadPageContent: page => {
            dispatch(loadPageContent(page))
        }
    }
}
const mapStateToProps = state => {
    return {
        categories: state.page.categories,
        pageContent: state.page.pageContent,
    }
}
export default connect(
    mapStateToProps,
    mapDispatchToProps
)(Category);
