How do I have a dynamically created and located popup menu display all of its options on the first button push?

I want a popupmenu to literally pop-up. I have a uitable. I want to allow the user to click a cell in the table and have a popup menu show up at the cell's location. The popupmenu and uitable are programmed, not created in guide. I have code that places the menu correctly, but only the first menu item shows up when you click on a table entry. On the second button push the entire menu shows up. I want the menu of choices to show up on the first button push, not require the user to click twice.

To be able to suggest an improvement, we have to see the code.

Adding to Jan's comment, how is the behavior you are seeing/expecting different from that of the last example in the uitable documentation? Pop-up menus which display all choices on the first click are generated.

f = figure('Position',[100 100 400 150]);

% Column names and column format
columnname = {'Rate','Amount','Available','Fixed/Adj'};
columnformat = {'numeric','bank','logical',{'Fixed' 'Adjustable'}};

% Define the data
d =    {6.125678  456.3457  true   'Fixed';...
        6.75   510.2342  false  'Adjustable';...   
        7      658.2     false  'Fixed';};

% Create the uitable
t = uitable('Data', d,... 
            'ColumnName', columnname,...
            'ColumnFormat', columnformat,...
            'ColumnEditable', [false false true true],...
            'RowName',[]);

% Set width and height
t.Position(3) = t.Extent(3);
t.Position(4) = t.Extent(4);
