dhx.ActiveContent,show controls according to the value

First,I want to show one or two buttons (for example one is delete button ,another is update

button) according to the returned different values in the elements of list, dataview, grid.

Secondly, when one button click , it would execute a function(the update_modal function) .I

want to transfer one parameter to the update_modal function , how can I transfer this

parameter?

I check samples\ui\list\11_active.html

There is a way to embed simple controls in the elements of list, dataview, grid.

There are my codes in the following:

dhx.ready(function() {
	dhx.protoUI({
		name:"activeDataview"
	},dhx.ui.dataview,dhx.ActiveContent);
	
    dhx.ui({
	id:"dd",
        rows: [
        {
                view: "activeDataview",
                id: "myActiveDataview",
                url: "long_list1.json",
                activeContent:{
                	oneButton:{
                                           id:"two",
											view:"toolbar", 
											 type:"subBar", 
											elements:[
								
											{
											view:"button",
											label:"updateBtn",
											id:"updateBtn",
											width:100,
											earlyInit:true,
											type:"round",
											click:"update_modal"
											},
											{
											view:"button",
											label:"deleteBtn",
											id:"closeBtn",
											width:100,
											earlyInit:true,
											type:"round",
											click:"delete_modal"
											}
											]


                      	},
					                	twoButtons:{
                                            id:"one",
											view:"toolbar", 
											 type:"subBar", 
											elements:[
								
											{
											view:"button",
											label:"updateBtn",
											id:"updateBtn",
											width:100,
											earlyInit:true,
											type:"round",
											click:"update_modal"
											}
								
											]


                	}
					
                },
				template:function(obj){
					if(obj.num=='1'){                 // according to obj.num ,show one button 
					return obj.title+"<br> <div style='float:right'>{common.oneButton()}</div>";
					}else if(obj.num=='2'){            //  show two button 
					return obj.title+"<br> <div style='float:right'>{common.twoButtons()}</div>";

				}
			
			}  ,
					type: {
                    width: "1000",
                    height:"auto"
                },
                select:false
         
        }]
    });
			
});

Thanks for help in advance !
