sapui5 - How execute code every time that I view a page

Question

I'm searching the mode to execute a code (in my case the retrieve of data to visualize from server) every time I view a page (every time the page is called by splitApp.toDetail or splitApp.backDetail). How can i do it?

P.S. The onBeforeRendering and onAfterRendering execute only the first time.

There is a solution for you. There is a event called routeMatched when navigation is triggered every time. You can attach the event in the detail page.

 onInit : function () {
    this._oRouter = sap.ui.core.UIComponent.getRouterFor(this);
    this._oRouter.attachRouteMatched(this.handleRouteMatched, this);
},

handleRouteMatched : function (evt) {
    //Check whether is the detail page is matched.
    if (evt.getParameter("name") !== "detail") {
        return;
    //You code here to run every time when your detail page is called.
}
